Abstract：Core-shell structured ZnS∶Cu/ZnS nano-particles and Cu2+-doped ZnS nano-particles without any shell were prepared, and the effect of ZnS shell on the luminescence properties of ZnS∶Cu2+ nano-particles was studied. The observed emission peak at 450 nm was assigned to the recombination of an electron from the shallow delocalized donor levels at the t2 level of Cu2+. The ZnS shell did enhance the luminescence at 450 nm, which resulted from the reduction of nonradiative recombination sites.
