Abstract

Cd1−xZnxS thin films were deposited on the glass substrates (GS) and on the potassium permanganate activated substrates (KMAS) at 350 °C using spray pyrolysis technique. X-ray diffraction studies confirmed that the films are polycrystalline and belong to the hexagonal structure. Scanning electron microscopic studies revealed an effective change on the surface morphology of the film due to potassium permanganate activation (KMA). Transmittance spectra of Cd1−xZnxS thin films were recorded in the range of 320–700 nm and the transmittance was found to be high for the film coated on KMAS than GS. Photoluminescence spectra show a strong emission peak at 585 nm for the film coated on the GS and it is shifted to 592 nm for the film coated on KMAS. Thus the results authenticate that KMA influences the structural and optical properties of the deposited films.
