ZnS thin films were deposited via RF magnetron sputtering and characterized using atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and ellipsometry. The nonlinear optical properties of these films were theoretically analyzed to assess their suitability for second-order nonlinear processes.
