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.
