Abstract: In this research, pure and various copper doped nickel oxide (NiO:Cu) thin films were prepared on glass substrate using spray pyrolysis technique. The FESEM images confirmed the formation of 50 nm grains that are reduced with increment of doping concentration. The XRD spectra showed all samples are polycrystalline cubic structure with (111) as preferred direction. The data analyses showed with increasing the impurity content the crystallite size of the films is decreased and the defect density is increased. These variations could be the reason for the higher optical sensitivity of the pure sample with a band gap of 3.6 eV to UV irradiation, compared to other doped samples.
Keywords: NiO, Cu-doped, spray pyrolysis, nano-structure, photoconductivity.
