Abstract
High-quality water-soluble near-infrared emitting quantum dots (QDs) are synthesized using a two-step approach for the first time. The CdS shell efficiently increases the structural stability of PbS QDs during water transfer and leads to good photostability and a significantly enhanced quantum yield as high as 30% in buffer.
摘要
首次采用两步法合成了高质量的水溶性近红外发射量子点（QDs）。CdS 壳在水相转移过程中有效地提高了 PbS QDs 的结构稳定性，导致良好的光稳定性和高达 30%的显著增强量子产率在缓冲液中。
