Abstract
Metal Sulfide nanoparticles have attracted considerable interest because of their unique
semiconducting and electronic properties. ZnS thin films have been deposited on glass substrates by spin
coating method with Zinc Nitrate as starting material. The samples were synthesized by mixing Zinc
Nitrate and Thiourea in Isoproponal. The crystal structure, orientation and surface morphology were
investigated by X-Ray diffractometer (XRD) and Scanning Electron Microscopy (SEM). XRD pattern
reveals the hexagonal structure of ZnS thin films. Optical properties were studied using UV-visible
spectroscopy. The film shows good optical properties with high absorption and energy band gap value.
These prepared films can be used for solar cell applications.
