Abstract

Undoped and Al doped CdS thin films were deposited successfully on glass plates using chemical bath deposition method at 80 °C with different Al concentrations between 0 and 8%. X-ray diffraction spectra revealed that undoped CdS thin film had cubic structure which was turned to mixed phase of cubic and hexagonal by Al doping. The noticed decrease in d-value, cell parameters, bond length and volume up to 4% of Al is due to the substitution of Al3+ into Cd-S lattice whereas the increase of these parameters beyond 4% is due to the formation of defects. Structural, optical and photoluminescence properties of Al doped CdS thin films were studied using X-ray diffraction, energy dispersive X-ray, ..
