PHOTOLUMINESCENCE STUDY OF ZnO NANOCRYSTALLITES WITH BN CAPSULES
氮化硼包覆纳米氧化锌体系的光致发光特性研究

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