The Optical Properties of Cadmium Sulfide Thin Film prepared by Electrochemical Deposition Technique

Abstract

Cadmium Sulfide (CdS) thin films were prepared by electrodeposition technique using a simple cell, on stainless steel and ITO glass as electrodes. The films were investigated by XRD . The XRD pattern indicated that CdS films possessing a polycrystalline hexagonal structure with lattice constants (a=4.223, c=6.684 A º). The optical energy gap of these films were calculated from the absorptance measurements (Eg =2.45 eV)
