摘要 | Crystal structure control is so important to the fluorescence properties that each element should be considered carefully. In conventional synthesis of ZnxCd1-xS alloyed nanocrystals (NCs), most of studies focus on ligand-surface interaction on the formation of either zinc blende or wurtzite ZnxCd1-xS nanocrystals, instead of the reactant source. In this work, mixed crystal phase was found easily in ZnxCd1-xS alloyed NCs when reaction proceeded at high Zn/Cd source ratio condition. Therefore, we regulate the Zn/Cd ratio to obtain relative pure zinc-blende structure, and study the influence of structure change on the fluorescence properties. Further, we have proposed a two-step ZnS coating method to acquire ZnxCd1-xS/ZnS NCs with separated crystal-phase between core and shell. Compared with maximum QY of 81% for ZnxCd1-xS/ZnS NCs synthesized by conventional one-step coating method, the performance of the optimized NCs has significantly improved with maximum QY of 93%. |
