Аннотация:The temperature dependences of the positions of maxima of exciton bands in the luminescence spectra of liquid crystal nanocomposites with CdSe quantum dots with sizes of 1.8 and 2.3 nm at T = 77-300K have been analyzed. The analysis under the theoretical model taking into account the electron-phonon interaction inside quantum dots has made it possible to calculate the values of the Huang-Rhys factor and average phonon energy in nanocrystals under study.
