Effect of deposition time on physical properties of ZnS thin films; prepared at a new condition

High quality ZnS thin films were deposited on glass substrates by a simple chemical solution method using tri sodium citrate as a new as well as nontoxic complexing agent for Zn2+ions. The effect of deposition time on thickness, morphology, compactness, particle size, transmittance values in the visible region and band gap energy of ZnS thin films were studied by scanning electron microscopy (SEM) and ultraviolet-visible (UV-vis) spectroscopy. The thickness of the prepared ZnS films could be controlled from 25 nm to 100 nm by changing deposition time from 2h to 6 hours.
