Summary:

Zinc Sulfide ( ZnS ) thin film is a promising material for its use in various electronical devices design which mainly exist in an α-phase ( hexagonal ) and a β-phase ( cubic ). In opto-electronics, ZnS materials ( II-VI groub compound ) can be used as light emitting diode in the blue to ultraviolet spectral region due to its wide band gap of 3.5 -3.7 eV at room temperature. In addition, in the area optics, ZnS can be used as a reflactor and dielectric filter because of its high refractive index ( 2.35 ) and its high transmittance (75% ) in the visible range, respectively. In this study, ZnS thin films were produced by spray pyrolysis as a function of different S : Zn molar ratio.
