Investigation of the temperature and precursors concentration dependence of the formation of ZnSe quantum dots
Abstract
Various variations of the synthesis of ZnSe quantum dots are investigated. The influence of temperature, the concentration of precursors and the time of synthesis of quantum dots was taken into account. Aliquot absorption spectra is measured for various time intervals and the dynamics of the growth of ZnSe quantum dots is estimated. Luminescence and absorption spectra were obtained for purified quantum dots. Based on the experimental data, the nucleation time of quantum dots, optimal methods of synthesis and growth control is determent. HRTEM images showed the average size of ZnSe quantum dot, the calculated band gap is 2.84 eV.
