Abstract

Abstract: Composite ZnO and ZnS nanostructured with Fe doping thin films, exhibiting high antimicrobial activity, have been synthesized by chemical route. The optimized parameters, including composition ratio, doping concentration, temperature, UV exposure, and thickness of the composite ZnO and ZnS films, have been optimized in thin-film form. The synthesized samples were identified and analyzed by XRD, HR-SEM, EDX, and HRTEM. The band gap was estimated from absorption spectra, and the Stokes shift energy was calculated from emission and absorption spectra. The conductivity of the samples increased with higher Fe content and it depended on the composite ratio of ZnO and ZnS. Antimicrobial properties were studied using four bacterial strains, revealing that a concentration of 3.5 wt% was the optimal value for the most efficient activity.
