Abstract
This Letter describes the photoluminescence properties of ZnO nanoparticles enclosed in BN capsules (ZnO/BN core/shell structure). PL enhancement of o ver one thousand times of ZnO/BN compared to pure ZnO nanoparticles was obs erved, which is attributed to the dielectric environment effects of the cap sule on the interfacial structures and defect amounts of ZnO quantum dots.
