Abstract

We reported the wet chemical synthesis of the ZnS: Mn nanoparticles capped with different capping agents. The growth in particle size was arrested using inorganic and organic capping without significant change in photoluminescence intensity and variation in band gap with or without shell and activator were calculated. The particle size was determined using TEM/SAXS and peak broadening of XRD was found between 10-20 nm..
