Abstract: | Cadmium sulphide ( CdS ) thin films were prepared by the chemical Spray Pyrolysis technique on glass substrates at 400°C. The analysis of x-ray diffraction spectra XRD , patterns indicated the presence of single-phase hexagonal CdS which confirmed through the atomic force micrographs (AFM) images. The structural parameters such as interplannar distance (d), lattice constant (a), grain size (D), and micro strain have been evaluated, The crystal growth became stronger and more oriented as seen in the x-ray diffraction spectra and grain size became larger with increasing in the thickness. The optical properties have been studied in the range (300-900)nm. It is observed that the direct band gap energy is inversely depended on film thickness from (2.36–2.34) eV |
