TUNABILITY OF STRUCTURAL, SURFACE TEXTURE, COMPOSITIONAL AND OPTICAL PROPERTIES OF CdZnS THIN FILMS BY PHOTO ASSISTED-CHEMICAL BATH DEPOSITION TECHNIQUE

摘要

Cadmium zinc sulfide (CdZnS) thin films have been deposited by chemical bath deposition (CBD) technique under dark, white light and fluorescent white light illuminated condition. Influence of light illumination on the chemical bath deposited CdZnS thin films was investigated by means of X-ray diffraction (XRD), atomic force microscopy (AFM), energy dispersive analysis of X-rays (EDX), UV-VIS-NIR spectrophotometer and photoluminescence (PL) emission spectroscopy respectively. Tunability of structural, elemental, surface and optical properties by the influence of light illumination on the growth of CdZnS thin films have been demonstrated in the present work
