Abstract

Fluorescence “blinking” kinetics of isolated colloidal InP quantum dots (QDs) are investigated via confocal single molecule microscopy. Analysis of fluorescence trajectories reveals inverse power law behavior (∝ 1/τm) in on/off time probability densities with mon ≈ 2.0(2) and moff ≈ 1.5(1). Such an inverse power law in both on/off times is inconsistent with a static distribution of electron/hole trapping sites and highlights the role of fluctuations in the QD nanoenvironment.
