ETN aims to acquire the recent and outstanding researches for the benefit of the human being.
Zinc Sulfide (ZnS) thin films were deposited on glass substrates at the pressure of 10-6 mbar by thermal resistor evaporation technique. The effects of annealing on the structural and optical properties of ZnS films were studied. Polycrystalline ZnS films have been analyzed by X-ray diffraction. Only hexagonal phase with the preferred (111) plane was found in ZnS films. Optical characteristics were studied as a function of annealing temperature and film thickness in air. The results show that the energy band gap was found to be about 3.5 eV. It was observed that the energy gap decreases with the increase in the film thickness and increases with the increase in the annealing temperature. Keyword: ZnS; Optical; Vacuum; Annealing.
