Summary of the invention
Thus, technical problem of the present invention is, document body and a kind of method that is used to make this document main body of a kind of method and a kind of device and a kind of secure file are provided, can preferably after manufacturing documentation main body itself, implement the color personalization with simple mode by this method and apparatus.
According to the present invention, the method for the feature of described problem by having claim 1, the secure file of feature with claim 11 and the device with feature of claim 22 solve.Favourable configuration of the present invention is by obtaining in the dependent claims.
Propose for this reason, use nano particle, these nano particles and electromagnetic radiation promptly with visible wavelength region in the interaction and the quantum mechanical effects of light relevant, described quantum mechanical effects is influenced by the form of described particle and/or the local concentration of nano particle.A kind of method that is used for secure file is carried out the color personalization has been proposed for this reason, described secure file comprises a document body, in this document main body, there is raw material, these raw materials are encouraged by the autotelic energy input of localization to provide or change nano particle partly, these nano particles produce color impression, wherein, the form of nano particle and/or concentration are relevant with the energy input in document body partly, wherein, the color impression of nano particle is relevant with the concentration of its form and/or part, in the method, energy is on purpose being introduced on such position partly: on this position, in document body, should cause colored color impression, so that by caused color impression store personalized information.A kind of secure file is provided thus, this secure file comprise one can the individual document body of color, in this secure file, there is raw material in inside at document body, these raw materials can on purpose be encouraged the nano particle that forms different shape and/or variable concentrations by means of the energy input of localization, and wherein, described form and/or concentration are relevant with the energy input, wherein, the color impression of nano particle is relevant with its form and/or its concentration.A kind of be used for to described secure file with secure file main body carry out personalized device comprise a document body acceptance division that is used to receive document body, one be used for energy input localization be incorporated into the energy source of document body, so that on purpose change color impression like this, the color impression that makes customized information pass through to be produced is stored in the document body.By being worked into when the manufacturing documentation main body together, raw material provides a kind of secure file in this document main body with can color individual document body.
In by the document body of a plurality of layers by means of laminated manufacturing, raw material for example can be incorporated between two layers before laminated on the printing technology.
Be interpreted as the size of nano particle on the one hand for the form of nano particle, be interpreted as the geometry of nano particle on the other hand.Be used in solid matter (Bulk) if in have preferably the nano particle of making less than the semiconductor substance of 2 electron-volts band gap and be usually expressed as so-called big or small quantization effect---particle size is varied to the more and more littler nano particle in several nanometers or the following scope.This semi-conductive nano particle is more little, and then band gap is big more.Thus, the size of band-gap energy and nano particle is a morphologic correlation.The absorption characteristic of electromagnetic radiation is associated with band-gap energy again.Thus, along with the variation of band-gap energy, the color of nano particle, the color impression that is promptly obtained when observing nano particle also change.For the nano particle of determining type, color impression is that the absorption characteristic of nano particle is influenced by the configuration of surface of nano particle mainly.In particle, motivate so-called surface plasma.These surface plasmas shape with nano particle fatefully are relevant.Under the situation of constancy of volumeization---only the variation, the variation of the ratio of vertical extensible extent and extending transversely amount of aspect ratio for example formed by to(for) little strip nano particle of the shape by nano particle are carried out, and the absorption characteristic of described nano particle can change relatively with wavelength.Color impression at first is meant the absorption characteristic of nano particle thus.In addition, self-evident for the professional, color impression also with volume in or the quantity of the nano particle that exists on the face relevant because in the number affects volume of particle or the overall absorption on the face.But the change curve of absorption spectrum does not change thus, but only absorption efficiency changes.If the variation in conjunction with the present invention mentions color impression then is not meant the variation based on the absolute absorption of rising/reduction.
The color impression based on its local concentration of nano particle changes and should be distinguished therewith.In the nano particle that absorption characteristic is mainly determined by the drive surface plasma in limit of visible spectrum, also additional have another and a concentration dependent effect, and this effect changes the wavelength dependence of absorption, changes the color of nano particle thus.At this, quantum mechanical effects works, described quantum mechanical effects influence each other based on: nano particle and under the situation that does not form chemical bond the quantum mechanics function of state of the electronic system of each nano particle change like this, make the absorption spectrum of these nano particles, its change color thus.Thus, in these nano particles, concentration does not cause stronger color impression, but causes transferring to the color impression of another color.This effect is referred to herein as nano particle concentration quantization effect.
Thus, by energy on purpose is input to the formation that can on purpose cause nano particle in the document body partly, promptly on purpose cause each color that provides or change and on purpose almost can regulate thus with localizing optical spectral region of nano particle.Can carry out the color personalization to secure file simply thus.
What need Special attention will be given to is, the energy that the most of system that is proposed does not need to be introduced begins or implement to cause the formation of the nano particle that color impression changes, and the described energy of introducing is not usually also as activation evergy.But raw material is incorporated in the document body like this, make this document main body prevention system under normal environment temperature form the nano particle of this generation color impression.Not for example to be easy to the bigger nano particle of symphysis one-tenth by being embedded into minimum nano particle stable in matrix, chemical solution or the analog.Thus, the surface of the nano particle of participation can reduce generally.This process is under an embargo in the document body and only just carries out by the position of energy input local heat at document body by being embedded at ambient temperature.
In a preferred implementing form, introduce energy by means of one or more laser instruments.Laser instrument provides advantage: the light of laser instrument can focus on well and therefore energy can on purpose be supplied with on focus with localizing.Can carry out color relatively in document body inside personalized and be not only to carry out from the teeth outwards with the material of making document body under the situation of selecting optical maser wavelength suitably.In addition, the energy input of carrying out by means of one or more laser instruments provides advantage: laser intensity and/or laser frequency can be modulated, so that the forming process that the control energy is imported and control causes the nano particle of desired color impression thus.
In a preferred implementing form, raw material comprises nano particle, and the band-gap energy of these nano particles is higher than the photon energy of visible light owing to big or small quantization effect.These nano particles of raw material can be impelled by energy on purpose being input in the document body to make these nano particle symphysis become bigger nano particle, therefore owing to big or small quantization effect changes its absorption spectrum and changes its color and color impression thus.
Thus, in a form of implementation, preferred feedstock is attached in the matrix.The preferred structure like this of this matrix, make the composition of raw material in matrix only when energy be input in the matrix and this matrix when being heated thus ability movable.
Propose in a particularly preferred form of implementation, matrix is made of Merlon, especially bisphenol-A-Merlon.Why especially suitable Merlon is, is because described Merlon is permeable for electromagnetic radiation in visible wavelength region.Yet can produce high like this radiant energy density by means of a laser instrument, make the Merlon material on purpose to be heated partly.
But in order to improve the absorption of laser, propose in a form of implementation of the present invention, raw material comprises activator species, and this activator species has good laser absorption ability.Activator species can reach such concentration: described concentration can influence the impression that sees through of document body sharply, but the autotelic absorption of the part of laser is obviously improved.Can mate optical maser wavelength, so that in activator species, realize good absorption.
Propose in a preferred further configuration of the present invention, activator species comprises zinc oxide ZnO.But also can use other material as activator species, for example carbon black or
Figure GPA00001016893100051
Propose in another form of implementation of the present invention, raw material additionally or as an alternative scheme comprises the precursor that is used to form nano particle, and the absorption characteristic of these nano particles is relevant with its form and/or its local concentration.This means that the color impression of these nano particles is relevant with its form and/or its local concentration.Thus, have such material as precursor in raw material: the growth that chemical reaction forms nano particle and/or causes the nano particle of the minimum that has existed takes place when being input in the document body at energy in these materials.In such form of implementation, by on purpose controlling the energy of being supplied with, not only the big I of the quantity of the nano particle that is provided but also described nano particle on purpose is affected.If high energy input is carried out at short notice, so that cause being heated to high temperature, for example 180 ℃ partly in material, then excitation forms the nucleus of big quantity.And if select the energy supply like this, make to obtain lower temperature, 120 ℃ temperature for example partly, a small amount of formation of new nucleus then only takes place, but the size growth of the nano particle that has existed under this very little temperature continues.
Thus,, can change local temperature and implementation procedure control thus in time, can regulate best desired color impression thus, be desired color by supplying energy on purpose.The II-VI semi-conductor nano particles is proved to be specially suitable material.But also known other suitable system or material, for example cadmium phosphide Cd 3P 2Or the like.Can use in principle in visible wavelength region show with the absorption characteristic of morphologic correlation, especially with the total material of size, shape and/or concentration dependent absorption characteristic (wherein, also referring to the variation (change curve that absorption spectrum with wavelength relevant) of absorption spectrum) according to concentration at this.
Be determined specially suitable II-VI semi-conductor nano particles and have big big or small quantization effect usually.For example the ternary compound or the quaternary compound of cadmium sulfide or mercuric sulphide, cadmium selenide or mercury selenide, cadmium telluride or tellurium mercury and above-mentioned element belong to preferred substance.For the formation that causes these nano particles or in order to support or encourage the size growth of the nano particle that has existed, raw material for example can comprise cadmium acetate and/or mercuric acetate and thioacetamide, form cadmium sulfide or mercuric sulphide when the input energy by it.
In another form of implementation, but raw material comprises the quantized nano particle of shape, and input changes its shape to these nano particles according to energy, and wherein, the color impression of these nano particles is relevant with shape.But the quantized nano particle of shape for example can be made of golden and/or silver-colored and/or its alloy.Raw material for example can comprise the nano particle of the little strip that is made of gold.These nano particles can be energized towards the direction of ball shape by the energy input and change.At this, mainly dominant absorption characteristic changes by the surface plasma excitation.
Especially the nano particle that is made of gold and silver alloy has and concentration dependent color impression.The absorption characteristic of these nano particles is relevant with the average distance that arrives adjacent nano particle.In a preferred implementing form of the present invention, raw material comprises the precursor of the material that forms colloidal nanoparticles, and the color impression of these colloidal nanoparticles is relevant with the local concentration of described colloidal nanoparticles.For example raw material can comprise zinc oxide (ZnO) and gold or silver salt.Under the situation that laser is injected, ZnO works as the electronics supplier, so that reduction gold or silver-colored.Thus, can encourage the growth of the nano-colloid that constitutes by gold and/or silver.
Carry out the introducing of energy like this, make especially depolymerization of chemical modification, pyrolysis or the carbonization of material of document body not take place.
In a preferred implementing form, there is optical pickocff, these optical pickocff monitoring color impression.So supply with according to the color impression control energy of being monitored.
Especially preferably on purpose be incorporated in document body on a plurality of position colocalization ground energy, so that form and/or concentration based on nano particle on described a plurality of positions cause color impression, wherein, described a plurality of positions produce a pattern, and this pattern comprises described customized information.Preferably on different parts, cause different color impression by the energy input.This means that the energy input is differently carried out on different parts.

Fig. 5 is used for secure file is carried out personalized device, but this secure file has a document body that color is individual.
The specific embodiment
Show case gesture 1a, 1b, 1c that is used for conduction band and respective tank gesture 2a, 2b, the 2c that is used for valence band for three different particle size a, b, c among Fig. 1.Width 3a, 3b between each case gesture 1a, 2a, 1b, 2b, 1c, the 2c, 3c are relevant with particle size respectively in box model.Particle is big more, and then corresponding case gesture is wide more.At this, particle a is minimum particle, and particle c is maximum particle.
If the energy level 4a～4c that the energy considering to obtain under the quantum-mechanical situation of definite conduction band is minimum respectively in these case gesture 1a～1c, 2a～2c or the highest energy state 5a～5c of valence band, then obtain different differing from 6a～6c for the particle a～c of different sizes, these can differ from and can unite with band-gap energy respectively.Can reduce along with the increase of particle size by difference 6a～6c.The band gap of a particle is big more, and then the energy of the radiation that is absorbed by this particle must be high more.
And being lower than the photon of band-gap energy, energy is not absorbed.This means, the red shift of ABSORPTION EDGE takes place along with the increase of particle size.This is schematically illustrated in Fig. 2.There, drawn the absorption of the particle of different sizes for wavelength.The ABSORPTION EDGE 11a of absorption curve 12a～12c～11c shows that the big wavelength of court moves along with the increase of particle size, i.e. red shift, and the increase of described particle size is represented by means of arrow 13.When changing, particle size demonstrates corresponding characteristic.
For cadmium phosphide Cd 3P 2, the band gap value is 0.55eV in solid.Under the situation of the medium particle diameter of 3nm, material no longer shows as black, but shows as brown.Along with further reducing of diameter, color is via red, orange and yellow variation, shows as white and has the band gap of about 4eV during at about 1.5nm up to material.
Schematically drawn the energy variation curve of conduction band 15 and valence band 16 among Fig. 3 respectively for particle size.Under the little situation of particle size, band-gap energy 17 is big, for example is in the scope of 4eV.This big or small particle shows as white.Along with the increase of particle size, band-gap energy 17 reduces and color changes to brownly via orange, redness from yellow, becomes black at last.
Similarly energy effect for example occurs in the gold particle of little strip.Schematically showing nano particle 21 among Fig. 4, the aspect ratio of this nano particle, is length 22 and the ratio of width 23 reduces.The nano particle of this strip, the nano particle that promptly has a wide aspect ratio for example are embedded in the matrix that is made of Merlon as raw material.If this matrix is heated, then nano particle is endowed the chance that changes its shape.The reducing of aspect ratio causes surface area to reduce, and causes the surface to reduce thus, and thus, originally this transformation of the nano particle 21 of strip is only stoped by matrix.Only when matrix and nano particle were heated, nano particle just was endowed the possibility that its shape is changed towards spherical form.At this, the volume of nano particle remains unchanged.Along with the variation of aspect ratio, the absorption feature of nano particle is also from the infrared visibility region that changes to.
Schematically show among Fig. 5 and be used for secure file 42 is carried out the individual device of laser 41, but this secure file comprises the document body 43 of a color personalization.Document body 43 preferably by a plurality of layer 44 by the laminated complex that constitutes.These layers 44 preferably are made of one or more thermoplastic plastic substances.Single layer or whole layer can be printed before laminated.In addition, microchip or other safety element can be worked in single layer or a plurality of layer.At least one layer, preferred a plurality of layers are structure like this, makes the raw material that is used to form the scalable nano particle of size be worked in the described layer.Nano particle also can for example be presented on the printing technology between two layers.A layer for example is made of bisphenol-A-Merlon.This material provides matrix for raw material.In this matrix, for example embed band-gap energy and be in the minimum nano particle of the material on the light photon energy.Additionally or as an alternative scheme can embed precursor, for example cadmium acetate and thioacetamide in matrix.For example zinc oxide ZnO is worked in the matrix as activator species.
Document body remains in the document body acceptance division 55.
Device 41 comprises that a laser instrument 45 is as energy source.The electromagnetic radiation that this laser instrument 45 produces in infrared range of spectrum, limit of visible spectrum and/or the ultraviolet spectral range.Laser instrument 45 for example can be selected from following inventory: and YAG:Nd (fundamental wavelength or multiple frequence rate: 1064nm, 532nm, 355nm, 266nm), Excimer-Lasers (F 2157nm, Xe 172nm), Exciplex-Laser (ArF 193nm, KrF 248nm, XeBr 282nm, XeCl 308nm, XeF 351nm), Titan-Saphir-Laser, CO 2-Lasers (10.6 μ m) or Diodenlaser.This laser emission 46 focuses in a zone of the layer 44 that is processed with raw material by an imaging optical device 47 localization ground.In focus 48, laser emission 46 preferably is activated the agent material, for example zinc oxide (ZnO) absorbs.This causes local hot spot (focus), and excitation forms cadmium sulfide thus, and this cadmium sulfide accumulates on the activator species zinc oxide (ZnO).Form the nano particle of different amounts according to laser intensity.Laser intensity is high more, i.e. the local rising of the temperature of matrix is high more, and the nano particle that then provides is many more.If select lower temperature, nano particle seldom then is provided or nano particle is not provided.But the growth of the nano particle that has existed continues.At this, the size variation of nano particle 49.Color impression changes according to size.
In another form of implementation, the radiation of activator species, for example zinc oxide (ZnO) is caused producing electron-hole pair, thus for example ionizable metal salt, especially silver (Ag +) and gold (Au 3+) be reduced corresponding metal and form nano particle.
Monitor eye impressions by means of the optical pickocff 50 that for example is configured to colourful CCD video camera.May need with light source 51 shot file main bodys 43 for this reason.The signal that detects by means of optical pickocff 50 is by control device 52 analyzing and processing, the energy input that this control device control is undertaken by the energy source 41 that is configured to laser instrument 45.In addition, energy source 41 can comprise a modulator 54, by the frequency and/or the amplitude of this modulators modulate laser, so that can control the input of energy in the document body 43.Modulator can be integrated in the laser instrument 45 in other form of implementation.
For the professional, energy source also can comprise a plurality of laser instruments, the light of these laser instrument emission different wave lengths.Can encourage different activator species best thus.
In other form of implementation, can propose, in a plurality of different layer of document body, be provided for changing the nano particle of color impression.If laser emission side by side or the time focus on the different parts in document body with staggering, so that on purpose import energy respectively partly and be provided at the nano particle that produces the visual color impression in the limit of visible spectrum, then can produce multicolour pattern in document body, this multicolour pattern shows customized information for example name, passport photograph or the like.
In some form of implementation, document body itself is secure file or valuable papers completely.In other form of implementation, document body for example is attached in the passport.
In some form of implementation, document body be by a plurality of layer through the laminated complex that forms, in this species complex, different layers comprise different raw materials and/or material concentration.Available thus simple mode causes different color impression by the energy input of localization in different layers.Described color impression can produce a multicolour pattern jointly.But these layers also can comprise identical raw material and/or material concentration.
For the professional, the present invention mainly uses in limit of visible spectrum.But also can consider to produce the form of implementation of the color impression that only is provided with for MACH CHK.On the one hand because caused color impression is in UV spectral region or the IR spectral region or because the absorption intensity of the nano particle concentration that produces is checked not high enough for the people.Be meant intensity situation rather than its change curve relevant of absorption at this with wavelength.At this, information also is stored by the variation of the color impression that changes relatively with wavelength.Only the quantity of the nano particle of the color change that is produced on purpose keeps very little.
Described form of implementation only is exemplary form of implementation.For the professional, there is multiple modification possibility.
