Indium doping effects on growth and preparation of spray pyrolysis deposited Cd_0.6Zn_0.4S thin films

Pure and indium doped in cadmium zinc sulfide cd_0.6zn_0.4s thin films were deposited onto glass substrate at different substrate temperature (275-375)c^0 , 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 c^0 and indium doping concentration of 5ml.
