Abstract: This paper studied the effects of nano and micro ZnO particles dopant on optical properties and structure of (PVA) films that were prepared for both pure and ZnO doped PVA using solvent casting method. The scanning electron microscopy is employed to characterize the morphology properties for the prepared samples. X-Ray diffraction technique was used to study the structure of films and the effect of ZnO doped on it. X-ray diffraction analysis confirmed that these films are polycrystalline structure nature. Optical energy gap PVA/ZnO films were calculated from absorptions spectra. It was found that the films exhibit indirect allowed transitions gap which decreased with ZnO particles doped.
