| 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. |
