Abstract

The invention relates to a process for producing a luminiferous composite based on amorphous chalcogenide semiconductor As2S3 and coordinative compound of europium(III), in the form of thin films and optical fibers, that can be used in the optoelectronic industry, namely for the manufacture of photoluminescent devices, for recording, transmission and amplification of optical information.The process, according to the invention, comprises the separate dissolution of semiconductor As2S3 and coordinative compound Eu(TTA)2(Ph3PO)2NO3 in propylamine or monoethanolamine at a temperature of 18…25°C, for 4…20 hours, mixing of these solutions to produce a composite in the following mass ratio, %: Eu(TTA)2(Ph3PO)2NO3 - 2.0…20.0, As2S3 - the rest, and homogenization at a temperature 18…25°C and a normal atmospheric pressure, for 20…30 hours. The resulting liquid mixture is applied on a substrate and dried at a temperature of 45…50°C for 3…5 hours.
