GROWTH AND CHARACTERIZATION OF CdZnS THIN FILMS BY SHORT DURATION MICRO WAVE ASSISTED-CHEMICAL BATH DEPOSITION TECHNIQUE

摘要

Cadmium Zinc sulfide (CdZnS) thin films have been deposited on to ultrasonically cleaned glass substrates with various Zn2+concentrations by Micro wave assisted-Chemical Bath Deposition (Mwave-CBD) technique. The structural studies were carried out by using X-ray diffraction (XRD) studies as a function of Zn2+concentration. The surface morphological/ surface texture of the deposited films was characterized by SEM and AFM analysis. The optical band gap (Eg) tunability of the deposited films for various Zn2+concentrations was successfully demonstrated by UV-VIS-NIR spectroscopy. The photoluminescence (PL) properties of the deposited CdZnS films have been investigated by PL emission spectroscopy
