| Abstract | ||
| ZnO Polycrystalline films were prepared on glass substrate by solvent evaporation at 25°C, and post annealed in air at range of annealing temperatures of (100, 200,300°C) for 1 hour. The samples were characterized by analyzing the structural and optical properties. X-Ray diffraction results reveal that the deposited ZnO films are polycrystalline in nature with cubic structure having (100) plane as a preferred orientation. The structural parameter such as the grain size, dislocation density, number of crystallite per unit area and stress were calculated for all films. The result shows that the change in deposited films properties is close to that of single crystal ZnO properties, with increasing the annealing temperature. Various optical parameters such as transmission, absorption coefficient and band gap energy have also been evaluated, the result of optical properties shows a direct allowed transition. | ||
