Nanoparticles of Mn and Pr-doped ZnS and CdS-ZnS were synthesized by wet chemical method and inverse micelle method. Physical and fluorescent properties were characterized by X-ray diffraction (XRD) and photoluminescence (PL). ZnS nanoparticles annealed optically in air shows higher PL intensity than in vacuum. PL intensity of Mn and Pr-doped ZnS nanoparticles was enhanced by the photo-oxidation and the diffusion of luminescent ion. The prepared CdS nanoparticles show cubic or hexagonal phase, depending on synthesis conditions. Core-shell nanoparticles enhanced PL intensity by passivation. The interfacial state between CdS core and shell material was unchanged by different surface treatment.
