Abstract
In this research, some of the structural and optical properties of the films study copper oxide CuO and doped with pure nickel weighting Doping ratios (1,3,5,7) % of water copper nitrate (Cu (NO3) 2.3H2O) and nickel chloride (NiCl2) and prepared a chemical Spray Pyrolysis method on glass substrates at (623 Κ °) and a thickness amount (120 nm) have been studied. The impact of doping with nickel (Ni) on the structural and optical properties of prepared films has been studied . The results of (XRD) tests showed that all the prepared films were of a polycrystalline installation and monoclinic crystal structure with a preferable direction was (¯111) ; and that the average of crystal size rates may decrease by increasing doping rates with a little change in the values of the lattice constants and the diffraction angles. The picture atomic force microscope (AFM) showed the values of the average of the surface roughness and the square root (RMS) increase when doping for all films. Through the record of transmittance and absorbance spectral by using spectrometer (UV-VIS) to the extent of wavelengths (200-1100 nm), it has been found that the absorbance increases , while transmittance decreased by increasing doping. It has also been found that the absorption coefficient increases by doping, while the optical energy gap for allowed direct transmission decrease by increasing doping with nickel (2.8-2.6) ev.
