摘　　要：CdS （cadmium sulphide） thin films have been prepared on glass substrate at 400 ℃ using home built spray pyrolysis apparatus. Aqueous solutions of cadmium chloride and thiourea were used for the cadmium sulphide films and different proportions by weight/volume of MnCl2·4H2O was used for doping Cd1-xMnxS （Mn onto cadmium sulphide） films. The films obtained are having continuous, smooth surface with good transmittance. The thickness of CdS film is of the order of 300 nm. Determination of the crystalline nature ＆ calculation of average grain size have been done using XRD pattern. The effect of Mn on the surface morphology of CdS film has been studied by scanning electron microscopy. The optical band gap has been calculated using the data from transmission spectra. Resistance before and after doping with Mn is also presented in the paper.
