Abstract

In the present work ZnS thin films with different concentration (0.25, 0.5, 0.75 and 1 M) have been deposited on glass substrates by sol–gel spin coating method using an acidic solution, containing zinc acetate (Zn(CHC3COO) 2.2H2O) and thiourea (CH4N2S) as precursors. The optical properties of ZnS thin films such as refractive index, extinction coefficient, dielectric function and band gap energy of the films were obtained by spectroscopic ellipsometry analyzes method in the wavelength of 300 to 800 nm. Considering the data obtained, it can be deduced that the optical properties of ZnS films is highly influenced by Zn concentration. The extinction coefficients (k) of the films were increase with increasing concentration of zinc acetate. From these results it is found that the energy gap of the ZnS films decreases with increasing concentration of zinc acetate in the range of 3.65-2.75eV.
