Abstract
In this work Zn1–x MnxS (x =0, 0.02, 0.05) nanoparticles were prepared by precipitation
method at room temperature. The cubic structure of the sample was identified from the X-ray powder
diffraction patterns and the average crystallite size is decreases on Manganese doping as compared to
undoped ZnSwhich is confirmed by field emission scanning electron microscope. Photoluminescence
spectrum infers that the increase in Mn concentration leads to increase in redemission. In addition, the
detailed study of both (gram positive, gram negative) bacteria andantifungal activity of the prepared
nanoparticles were tested for its efficiency.
