Abstract: Studying on the structural properties, surface topography of compounds (ZnO 50%) and (CdO 50%) nanoparticles prepared by the method of chemical deposition, Before and after annealing at (600?) . Thin films with the same weight ratios were also prepared and deposited by the method of rotational coating and indicating them at different temperatures and the (600?, 400?, 200?) extent of their impact on On optical properties. The results of the X-ray diffraction showed (XRD) that all the results are of hexagonal crystal structure, and the topography of the surface was studied with the scanning electron microscope technique (SEM) and the impact of the annealing time on the loss of atomic weights of the chemical elements used in preparing the samples according to the technique (EDAX), or from the visual results, the value of the energy gap appeared if it appeared (3.614 eV) before annealing, but its value decreases with the increase in the annealing temperature, from which it changed to (3.551 eV3.349 eV), and (3.40 eV) with the change in the annealing temperature from (200?, 400?, 600?) respectively. This research aims to develop new materials with improved properties by controlling annealing processes, which enhances their use in many areas of advanced technology.
