| Abstract | ||
| Thin films of ZnSe were deposited on glass substrate by thermal evaporation, effect of annealing temperature on the X-ray diffraction and optical properties of the films have been investigated. X-ray diffraction shows that prepared films are polycrystalline with preferred [111] orientation and having a zinc blend cubic structure. The lattice constant has been evaluated for ZnSe, it's value was found to be decreasing with annealing temperature and then after returns to increases. From optical measurement, it found that optical band gap have unstable changes with annealing temperature while the absorption coefficient increase with annealing temperature | ||
