Abstract
The growth behavior of CdTe quantum dots (CdTe QDs) prepared in aqueous solution by atmospheric microwave reactor and oil-bath were studied. The activation energy values for the ripening were evaluated for CdTe QDs. In addition, the effects of experimental parameters such as microwave power, capping ligands and pH values on the growth of CdTe QDs were also studied. XRD, TEM, Absorption and photoluminescence spectra results show that the size, shape, growth rate and luminescence of the obtained CdTe QDs are almost the same and that microwave irradiation could enhance the size distribution but could not reduce the activation energy nor change the reaction kinetics. The growth rate is strongly dependent on the nature of the capping ligands and pH value and is independent of microwave power.
