Abstract

Cu doped CdxZn1-XS thin films have been produced by Spray Pyrolysis technique at 2750C±50C. This work describes structural, surface morphology and optical (UV-Vis) properties of as-deposited Cu doped CdxZn1-XS thin films as a function of Zn in the solution. It has been observed that CdZnS films have hexagonal structure and the grain sizes are found to increase with increasing Zn content in the solution. The energy band gap values obtained are 2.330, 2,447, 2.716, 3.044 and 3.519eV for Zn as 0, 25, 50, 75, and 100% respectively.
