We demonstrated that by properly coupling to silver nanoprisms, single CdSe/ZnS semiconductor quantum dots (QDs) exhibited suppressed blinking behavior, an enhanced fluorescence intensity ( approximately 2.5 fold), increased radiative decay rates ( approximately 12.5 fold), and antibunching single-photon emission. All these modifications significantly promote the overall performance of the proposed single-photon sources based on colloidal semiconductor QDs.
我们证明，通过适当耦合到银纳米棱镜，单个 CdSe/ZnS 半导体量子点（QD）表现出抑制的闪烁行为、增强的荧光强度（约 2.5 倍）、增加的辐射衰减率（约 12.5 倍）和反聚束单光子发射。所有这些改进都显著提高了基于胶体半导体 QD 的单光子源的整体性能。
