Abstract

Procédé de préparation d'un écran d'observation luminescent, qui consiste à déposer sur un support une matrice absorbant la lumière; déposer sur cette matrice et sur ce support une couche de particules de luminophores, et revêtir cette couche de particules de luminophores d'une pellicule d'un polymère organique, ce procédé, destiné à enlever totalement ladite couche de particules de phosphore et ladite pellicule tout en laissant sans dommage notable ladite matrice, étant caractérisé en ce que l'on met en contact cette pellicule avec une solution alcaline aqueuse ayant un pH compris entre 8,0 et 13,0, jusqu'à ce que le matériau constituant la pellicule soit, au moins partiellement, solubilisé, et en ce qu'ensuite, on lave ledit support à l'aide d'un milieu aqueux jusqu'a ce que la pellicule et la couche de particules de luminophores soient sensiblement éliminées.
