Temperature dependence of the luminescence spectra of liquid crystal composites with CdSe quantum dots

Abstract

Cadmium selenide quantum dots chemically synthesized in a cadmium caprylate liquid crystal matrix are investigated by means of confocal microscopy. The dependence of the luminescence spectra on temperature in the range of 77.3–300 K, on quantum dot size, and on sample inhomogeneity is investigated.
