Antibunching Single-Photon Emission and Blinking Suppression of CdSe/ZnS Quantum Dots

Abstract

We demonstrated that by property coupling to silver nanoprisms, single CdSe/ZnS semiconductor quantum dots (QDs) exhibited suppressed blinking behavior, an enhanced fluorescence intensity (similar to 2.5 fold), increased radiative decay rates (similar to 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.
