Optimization of chemical bath deposited CdSSe thin films

Abstract

CdSSe nanoparticles were organized by chemical process at ambient conditions. XRD analysis confirmed that CdSSe NPs. The UV-VIS absorption spectra for CdSSe nanoparticles shown .The range of the absorption edge lies between 650 nm to 420 nm, which is apronounced blue shift from 712 nm of the bulk CdSSe indicating that particles in nanoscale. There is a blue shift compared with the bulk CdSSe because of the quantum confinement effect. The Photoluminescence emission spectra of CdSSe nanoparticles at the different excitation wavelength are show.
