Abstract

Thin luminofore layers of nanocomposites (NC) on a base of copolymer styrene and butylmethacrilate (SBMA) and of organic luminofores 5-(4-dimethylamino-benzylidene)-pyrimidine-2,4,6-trione (PI) or 3-(4-dimethylamino-phenyl)-1-(4-isothiocyanato-phenyl)-propenone (PII) are obtained. The dimensions of PI and PII particles are less than 100 nm and they are uniformly distributed in a matrix of polymer. The absorption of NC reveals bands of absorption with maxima at 470, 432 and 340 nm for PI-SBMA and 443 nm for PII-SBMA. The photoluminescence (PL) of NC reveals an intensive wide band at 532 nm for PI-SBMA and 5 bands at 450, 490, 518, 640 and 700 nm for PII-SBMA..
