Abstract

Effect of nickel doping was investigated on doped CdS films by spray pyrolysis technique and examined by XRD, AFM, and UV-VIS spectroscopy. The increasing of Ni doping ratio improve (020) preferential orientation. XRD analysis confirmed the CdS nanostructure for all samples. The crystallite size for pure CdS showed an increase from 19.98 nm to 27.04 nm on doping, whereas the strain (%) parameter was decreased from 25.0 to 13.3. AFM images offer a decrease in roughness from 6.5 nm to 3.48 nm with Ni – 4% content. Transmittance was exceeding 70% in the visible range by Ni content. Also, the bandgap was decreased from 2.4 to 2.3 eV with the increment of Ni content.
