Title:
SILVER HALIDE MATERIAL FOR OPTICAL MEMORY DEVICES WITH LUMINESCENT READING AND METHODS FOR THE TREATMENT THEREOF
Document Type and Number:
WIPO Patent Application WO1998037456
Kind Code:
A8
Abstract:
This invention concerns a luminescent optical memory material and method of forming this material, including the encoding of information by a photographic process. The method involves the use of silver halide crystals of a defined size range, with the optional use of sensitizers, emulsion stabilizers, and other agents followed by the absorption of luminescent dyes on the developed silver particles to form a luminescent optical memory system. The method involves synthesis of a photographic emulsion with silver halide crystals of a defined size range, applying photographic emulsion to a substrate, exposing to light photochemical treatment and a process of transformation of the silver particles formed in the places exposed by light into luminescent particles. The method involves obtaining a multi-layer luminescent material for three-dimensional optical memory devices.
