In this research we prepared ZnO thin films by Spray pyrolysis method with thickness (300nm) on a glass substrates and study its optical and electric properties. The results of (X-Ray ) diffraction showed that the films have a polycrystalline structure , The Absorption and The transmission as a function of photon energy for ZnO films had been studied , The investigated of energy gap of the direct allowed transitions of ZnO film showed a value of (3.14 eV). The optical Absorption coefficients have been study as a function of Photon Energy. See beck measurements revealed that ZnO thin films are n-type.
