RESEARCH OF PHOTOLUMINESCENCE SPECTRUM EVOLUTION AS A METHOD OF THE PROCESSES PROPAGATION OF COLLOIDAL QD ANALYSIS

It was offered an analysis method of quantum dots propagation dynamic from the photoluminescence spectrums evolution of solutions. This method makes it possible to obtain necessary measurement results without retrieving probe samples from reactor. It was presented the results of the PbS nanoparticle propagation research in the Pb(CH3COO)2 and CS(NH2)2 precursor reaction mixture unstabilized by surfactants. Time windows and features of formation stages of nanoparticles with different sizes were determined by changing intensity and wavelength of photoluminescence spectrum maximums.
