Nanocrystalline CdS thin films were successfully prepared using simple chemical bath deposition technique. Cadmium sulphate, thiourea and deionised water were used as starting precursor solution. The prepared thin films were characterized using X-ray diffractogram (XRD), Scanning electron microscope (SEM), elemental composition using energy dispersive spectrophotometer (EDAX) and optical band gap (UV-Spectroscopy).X-ray diffractogram reveals that present of cubic and hexagonal phase. The thickness, crystallite size and grain size were observed to be increase with increase operating temperature of bath while optical band gap energy slightly decreases. Effect of deposition temperature on physical, structural, microstructural, electrical and optical properties of these films was studied and presented in the present investigation. Prepared thin films shows good response towards photoconducting in presence and absent of light.
