Abstract Pure and Barium doped Cadmium Sulphide (CdS) thin films are grown by the chemical spray pyrolysis (CSP) technique. The films are characterized using X-ray diffraction (XRD), UV-VIS spectroscopy and Atomic Force Microscope (AFM). The XRD shows that pure and doped films are polycrystalline. The average grain of films was found to increase with Barium doping. The optical investigation shows a small decrease in bandgap value for the doped films. The pure and 2% and 4% Ba doped films were found to have a bandgap of 2.43eV and 2.5 eV respectively.
