Indium doping effects on growth and preparation of spray pyrolysis deposited Cd0.6Zn0.4S thin films

Abstract

Pure and Indium doped in Cadmium Zinc Sulfide Cd0.6Zn0.4S thin films were deposited onto glass substrate at different substrate temperature (275-375)C0 , at different Indium doping concentration (1-10) ml by spray pyrolysis technique , using precursor solution of Cadmium Chloride , Zinc Chloride , and Thiourea as Cadmium , Zinc and Sulfide source respectively The effect of Indium doping on the structure and morophology of prepared thin films have been investigeted . X-ray diffraction (XRD) , scanning electron microscope (SEM) have been used examining these samples .XRD studies , have revealed that the films are polycrystalline , with preferentid orientation of the crystallites in film grown producing a strong hexagonal (002)or cubic (111) peak . the grain sizes were found in the rang of (175-339.68)nm and (214-258) nm depending on Indium dopinconcentration and annelingtemperature. And these results have been confirmed by scanning electron microscope . The best crystallinity of the films was obtained at the substrate temperature of 350 C0 and Indium doping concentration of5ml.
