الخلاصة

Cadmium Sulphide (CdS) thin films are produced using spray pyrolysis deposition technique. Films are annealed in air at 400, 500, and 600 K of 1 h. It characterized by X-Ray Diffraction (XRD), Atomic Force Microscope (AFM) and optical properties of CdS. XRD shows that these films are polycrystalline in nature with cubic and hexagonal crystalline structure. The crystallite size, microstrain, and dislocation density were measured. AFM shows that the total substrate surface is finely covered with uniformly distributed spherical shaped grains. Optical transmittance was shown that direct transition with band gap energy was decreased between 2.44 to 2.27 eV with annealing.
