Abstract

ZnS:Mn/ZnS core/shell nanoparticles were pre-synthesized by microemulsions technique. To prepare water-soluble and biocompatible nanoparticles, thioglycolic acid was directly added into the same reverse microemulsion system to modify the surface of ZnS:Mn/ZnS nanoparticles. The functionalized ZnS:Mn/ZnS nanoparticles were coupled with carboxyl and revealed farther luminescence enhancement at 600nm. The experiment results indicated that passivating of the organic molecules and the polynuclear complex of Zinc may be the possible mechanism leading to enhancement of luminescence.
