  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
