Abstract

CdSe/ZnS quantum dots in solution ad in condensed phase have been investigated by methods of laser induced luminescence. Anti-stokes photoluminescence (APL) of CdSe/ZnS nanoparticles in the solutions and in the films has been studied under action of laser radiation of various wavelengths. The dependencies of APL of CdSe/ZnS nanoparticles ensembles on exciting radiation intensity, temperature and quantum dots concentration have been studied. It is shown that the mechanism of APL formation in CdSe/ZnS nanoparticles is thermal.
