Microstructural and optoelectronic properties of diluted magnetic semiconducting Cd1−xFexS nanocrystalline films

► The microstructural and optical properties of Cd1−xFexS thin films were studied. ► The micro structural parameters of the films have been determined. ► The room temperature reflectance and transmittance data are analyzed. ► The refractive index and energy gap are determined. ► The single oscillator parameters were calculated.
