The synthesis of CdS nanocrystals was performed directly inside of polymeric matrix at $T=313$ К. The photoluminescent spectra of the samples obtained were investigated at different temperatures and different intensities of optical excitation. A mechanism of the radiative recombination of nonequilibrium charge carriers responsible for certain photoluminescence bands of CdS nanocrystals is discussed in this paper.
