摘要/描述

We report detailed experimental studies of enhanced fluorescence intermittency in Mn-doped single ZnSe quantum dots. A The measured intermittency statistics and its dependences on the excitation intensity and dot size indicate that the enhanced blinking might be due to the strong coupling between the multiple Mn2+ ions within a single nanocrystal. A The measured statistical results are compared with a diffusion-controlled electrontransfer model, which gives the diffusion rates for the "on" and "off" time distributions.
