In this research, Co3O4:Ni thin films have been prepared by a chemical spray pyrolysis method (CSPM). The synthesized samples, structure and morphology of creating Co3O4:Ni thin films were characterized by X-ray diffractions (XRD), and Atomic Force Microscopy (AFM). The impacted of Ni concentration were changed from 0 to 4 % by XRD results cause increasing the crystallite size, while the Microstrain and the dislocation density are decreasing. Furthermore, the AFM imaging shows of Co3O4:Nithin films involving a classic amorphous polymer-metal complex synthetic route where Co3O4 films are uniformly embedded with 3D nanoparticles Ni skeleton. The optical properties approve that the energy gap increased from 2 eV to 2.5 eV at 4% Ni doping.
