Abstract
PURPOSE:To enhance the absorptivity to light of a visible-near IR range or reflectivity and to improve the light control function of a device by providing a tungsten bronze film on the surface of the fine particles of anisotropic dipoles. CONSTITUTION:The fine particles of the anisotropic dipoles having the tungsten bronze film on the surface are used as the fine particles of the anisotropic dipoles. The tungsten bronze has a broad absorption band in the visible-near IR range based on the inter-valency transfer and absorption between W(V) and W'(VI) and is, therefore, colored strongly blue. Since part of the electrons of the crystallized tungsten bronze be have freely electronically, the reflectivity to the light of the visible-near IR range is greatly enhanced. The light control function is thereby enhanced.
