On the impact of the laser radiation wavelength and the concentration of quantum dots on the luminescence spectra of colloid solution and QD-doped nanocomposites

The influence of the concentration and the laser excitation wavelength on the width and luminescence spectrum maximum of CdSe/CdS /ZnS quantum dots in the toluene solution and doped on the glass plate was studied. It was shown that the wavelength of the exciting laser does not affect the width and peak center of the luminescence spectrum of the samples under the study. Possible mechanisms of the quantum dots concentration influence on studied parameters are analyzed
