Abstract
Composites based on polyvinylchloride with incorporated CdSe/ZnS nanoparticles are produced. The optical and electrical properties of the polymer composites containing CdSe/ZnS nanoparticles are studied. The absorption and photoluminescence spectra of the composites are recorded, and their bulk resistivities are measured. The CdSe nanoparticle dimensions are determined. It is established that, upon short-term heat treatment, the photoluminescence intensity increases, whereas upon heating for a long time, the photoluminescence intensity substantially decreases.
