Unique properties of nano-particles of Mn-doped ZnS prepared by a new chemical process are studied. Homogeneously Mn-doped ZnS nano-particles, as demonstrated from electron spin resonance (ESR), were accomplished by precipitation in a methanolic media with the aid of methacrylic acid at room temperature. Photoluminescence (PL) intensity of ZnS nano-particles increased with decreasing particle size. Quantum size effects were confirmed from the blue shift in the optical band gap of ZnS nano-particles. The enhanced PL intensity was also explained by the nanosize effect.
