Figure 8

Fluorescence emission from representative individual ZnS-capped and OPV-covered CdSe quantum dots. The size of the quantum dot was 4.3 nm in both cases and the integration time of the experiment was 2 s. The dotted lines indicate the 2σ noise threshold of the experiment. When emission was below this cutoff the quantum dot was defined as residing in a “dark” or “off” state
