Study of the Optical Properties and Structure of in Thin Films Copper Oxide Doped with Zinc Oxide

Nano Copper oxide doped (2,4,6,8)% (CuO) thin films were fabricated on glass slide substrates at (4000C) by spraying method using a solution containing Copper (II) oxide, Copper nitrate and water. The effect of Zinc nanoparticles (ZnO) on the structural and optical properties of (CuO : ZnO) thin films were studied, the structural properties were studied by X-ray diffraction (XRD). The results show that all the samples have a cubic structure. After (ZnO) doping, The topography properties were studied by scanning electron microscopy (SEM) while optical properties were studied by Uv-vis spectrophotometer. The optical transmittance has been decreased, the optical band gaps of (CuO) doped (ZnO)thin films decrease as the(ZnO) content increased.
