In Chemical bath deposition technique, the cadmium chloride and thiourea solutions were taken in a basic medium (pH ~ 11.8) at 90oC for 4 hours. The Cds thin film was prepared on glass substrate. The structural and morphological properties of films obtained by CBD were investigated using X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Energy Dispersive X- ray Spectroscopy (EDAX) and Atomic Force Microscope (AFM). X - ray pattern showed that the CdS thin film deposited without any complex agent was grown on an amorphous phase. SEM image showed that the CdS thin film deposited homogeneous, uniform grain size and good adhesion to the substrate.
