Abstract: 

ZnS nanolayers were deposited on clean glass substrates at different temperatures, by either physical vapor deposition (PVD) or spray pyrolysis (SP) method. All the samples were annealed in air at 5000 C. Optical and structural properties of the thin films were examined by UV/v is spectroscopy and XRD analysis. Band gaps of the ZnS thin films are obtained from the spectroscopy data. XRD analysis shows that all the films have a cubic structure. By annealing, crystallinity of the samples is improved and the grain sizes are increased. Transparencies of the samples become lower as the films thickness is increased. However, the PVD samples are higher and the SP ones lower transparent through the annealing process. Different behaviors of the samples to the annealing process and film thickness are also discussed.
