[7p-PA7-16] Hydrothermal synthesis of highly luminescent ZnSe quantum dots
Keywords:ZnSe quantum dots, core/shell quantum dots, hydrothermal synthesis
Highly luminescent ZnSe-based quantum dots (QDs) were synthesized by a hydrothermal method. The characteristics of the ZnSe precursor solution strongly influenced the photoluminescence (PL) quantum yields (QYs) of the QDs. The PL QY of ZnSe-core QDs synthesized under the optimum conditions reached 60%. Furthermore, the PL QY further increased to higher than 90% when a ZnS shell was applied to prepare ZnSe/ZnS-core/shell QDs.
