Structural and optical properties of ZnS/PVA and PB doped ZnS/PVA Nanocomposite films

Author:

Shanmugam, G., Ashok Kumar, S., Bhaskar, R. S. and Moses. V. G. Isaiah

Subject Area:

Physical Sciences and Engineering

Abstract:

ZnS/PVA and Pb doped ZnS/PVA nanocomposite films were synthesized using in-situ chemical method. X-ray diffraction patterns of the films confirm the cubic structure of ZnS. Optical absorption studies exhibit the red shifted phenomenon with the comparison of absorption peak of bulk ZnS. The optical band gap energy increases with increasing Pb dopant concentration. Photoluminescence spectra of the ZnS/PVA and Pb doped ZnS/PVA nanocomposite films show the two emission peaks in the visible region.
