Abstract | ||
Zinc selenide (ZnSe) thin films were prepared by spray pyrolysis technique on glass substrate at substrate temperatures of 380, 400 ºC and then annealed in 400 ºC .Structure of the samples were studied by XRD and UV-Vis spectroscopy was used to investigate the optical properties. The results of the XRD data indicated that the samples are amorphous before annealing with small ZnO phase, but after annealing the optical studies showed that the band gap of the sample decreases and approached to the ZnSe band gap value. The one which was grown at 400 ºC substrate temperature is polycrystalline ZnSe with prefer orientation of (111). | ||
