Abstract

In this research, ZnS nanostructure Thin films with thicknesses of 130-210 nm were prepared on glass substrates at 70 by chemical bath deposition method. In this method, thioacetamide and triethylamine were used as a S-2 source and a completing agent instead of ammonia, respectively. The effect of changes in concentration ratio of thioacetamide to zinc as well as deposition time on structure, surface morphology, particle size, thickness and optical properties of the layers were examined by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM) and ultraviolet-visible (UV-vis. ) spectroscopy. UV-vis. spectroscopy data showed the prepared ZnS films to have more than 70% transmission in the visible region and an optical band gap ranging from 3. 75 to 4. 1 eV. XRD results revealed that the obtained films were highly crystalline with a cubic structure. FE-SEM images showed that the surface of the films was covered with homogenous, dense and fine spherical nanoparticles.
