Synthesis and optoelectronic properties of CdSe quantum dots
Abstract
A series of Cadmium Selenide nanoparticles in the range of 6-12 nm have been synthesized by a wet chemical route that employs Mercaptoethanol as a capping agent. These nanoparticles have been characterized by Ultraviolet-visible (UV-VIS) absorption, photoluminescence spectroscopy, and X-RAY diffraction (XRD). The effect of concentration on the optical spectra has been investigated whereas Mercaptoethanol which is a growth-limiting agent, prevents bulking. The augmentation of concentration of Mercaptoethanol decreases the size of Cadmium Selenide nanoparticles and shifts the peaks of absorption spectra
