Growth and Optical Properties of ChemicalBath Deposited Cd_(0.7)Zn_(0.3)S Nanoparticles

摘要

In the present work thin films of Cd_(0.7)Zn_(0.3)S ternary compound have been deposited onto glass substrates by chemical bath deposition method at 300°K (room temperature). The structural morphology of the synthesized compound was studied using XRD, TEM as well as SEM techniques. XRD shows the prepared CdZnS are polycrystalline having wurtzite type structure. TEM and images exhibit a uniform distribution of hexagonal shaped particles. EDS confirms the formation of ternary semiconductor from the compositional analysis. The particle size measured from TEM & SEM shows the agglomeration of nanoparticles with a larger particle 45-65 nm. UV-VIS measurement shows prominent absorption peak at 474nm along with 734nm The Photoluminescence exhibit the band edge emission at 490 nm along with other blue-green emissions.
