Synthesis of ZnS Thin films Using Electrochemical Deposition Technique

Authors- Sanjay Kumar Dubey, A. K. Jaiswal

Abstract-Zinc sulfide thin films were synthesized by means of cyclic voltammetry technique onto stainless steel substrate. Cyclic voltammetry was employed to measure its ranges of deposition voltages and thickness of ZnS thin films can be controlled by number of voltage cycles applied during deposition. The bath temperature has used at 500C. The Influence of bath temperatures on optical properties and morphology has been investigated in details. The electrochemical deposited ZnS thin films were characterized by UV-visible spectroscopy and the field emission scanning electron microscopy (FESEM). The UV-visible spectroscopy analysis showed that energy band gap has found 3.73 eV depending at (500C) bath temperature. The FESEM analysis showed that ZnS thin film deposited at (500C) bath temperature is polycrystalline nature, homogenous, uniform with randomly oriented nanoflakes and nanorods. The good quality of zinc sulphide thin film could be prepared in the presence of triethanolamine.
