Abstract
ZnS nanopartices have been extensively studied during the last decade due to their unique optical and electrical properties, which are come from quantum confinement effect. In this study, ZnS nanoparticles on the monodisperse spherical silica particles (ZnS@silica) were synthesized and covered with silica layer on its surface (silica@ZnS@silica). Their optical, structural properties, surface morphology, and quantitative analysis were investigated by PL instrument, XRD, SEM, TEM, EDX, respectively. The trend of optical properties-photoluminescence were examined by the regulation of sulfur vacancy.
