Preparation of Semiconductor Nanoparticles (CdZnS) by Chemical Precipitation Method

This study explains the preparation of semiconductor nanoparticles CdZnS by the chemical precipitation method. UV visible spectrum for the prepared nanoparticles was analyzed. The band gap energy is determined using the Tauc plot equation. The Refractive index of the material was also deduced from the spectrum. The Group 2-6 semiconductor nanoparticles were synthesized by the chemical precipitation method. The optical studies were done for the prepared sample. We performed the product characterisation by UV- Visible Spectroscopy; the band gap energy was calculated using the Tauc plot. The refractive indices of the particle were calculated using various equations and plotted band gap energy versus the refractive index of the material.
