Preparation of CdSe Quantum Dots using kinetic growth method

Abstract

High quality quantum dots have been prepared with advances in the modern colloid chemistry. In the present study we have focused on preparation of CdSe quantum dots (QDs).CdSe prepared via colloidal synthesis in aqueous medium. CdSe QDs optical properties and size were characterized by ultraviolet-visible (UV-vis) absorption spectra, Photoluminescence spectra and DLS measurement. The result showed that the absorption spectra clearly indicate the absorption peak shift from 500 nm to 650 nm on increasing. The particle size average diameter of the CdSe quantum dot is reported as 13.36nm.
