Method for producing a luminiferous nanocomposite based on coordinative compound of terbium(III) and poly-N-vinylpyrrolidone

摘要

The invention relates to the technology for prodicing nanocomposite materials used in the optoelectronic industry, namely for the production of photo- and electroluminescent devices, for recording, transmission and amplification of optical information.The method, according to the invention, includes the separate dissolution in methanol for 6…8 hours of Tb(TTA)2(Ph3PO)2NO3 at the temperature of 60°C and poly-N-vinylpyrrolidone at the temperature of 18…25°C, mixing and homogenization of methanol solutions of Tb(TTA)2(Ph3PO)2NO3 and poly-N-vinylpyrrolidone, in a mass ratio, %: Tb(TTA)2(Ph3PO)2NO3 - 0.2…20.0 and poly-N-vinylpyrrolidone - the rest, at the temperature of 18…25°C for 20…24 hours. Then, the resulting liquid mixture is dried on a substrate at the temperature of 65…70°C for 3…5 hours.
