Abstract: Thin films of ZnS-PVA nanocomposites have been prepared by chemical bath deposition (CBD) method by varying the concentration ratio of sulphur to zinc sources. The obtained films are characterized by XRD, TEM, UV-visible spectra, photoluminescence (PL) spectra and current-voltage (I-V) characteristics. The results show strong dependence on source concentration ratio. There is an increase in particle size and decrease in band gap with increase of S to Zn source ratio. PL spectra show decrease in intensity and blue shift with the increase in this ratio.
