摘要：
Zinc sulfide (ZnS) thin films were deposited on glass substrates by radio - frequency (RF) magnetron sputtering technique at pressure of 10(-6) torr. The deposition parameters were optimized and the films were annealed in air atmosphere (300 degrees C for 1hr). The obtained (as-deposited and annealed) thin films were characterized for structural and optical properties. The thickness of the films was calculated by ellipsometry. XRD patterns revealed that the films were crystalline in nature with hexagonal structure. The morphological characteristic was carried out by optical microscopy. The optical absorption studies in the wavelength range 300-900 nm show that energy band gap of the film was found to be decreased with the annealing temperature.
