Abstract

In this work, we present experimental evidence and analytical studies of the XRD patterns and optical characterizations of ZnS films with different optical thicknesses. Thin films of ZnS were deposited on glass substrates by thermal evaporation. The crystallite size increased as the optical thicknesses. The overall absorbance has been increased with the film thickness and the direct band gap was obtained. It decreases with the increasing in the thickness of the films.
