The fluorescence of single semiconductor quantum dot (QD) nanoparticles exhibits "blinking" between bright and dark states. This behavior is due to the transfer of photoexcited charge carriers from the QD core to trap sites on the QD surface or external to the QD. Spatially correlated fluorescence and AFM has been used to study this behavior for individual QDs and small QD aggregates. It was found that small QD aggregates exhibit blinking behavior that is greater than the sum of its parts. The blinking occurs much more rapidly and with greater intensity than would be the case for an equivalent number of QDs blinking independently. This is attributed to trapped electrons from one QD altering the fluorescence characteristics of neighboring QDs. Spatially correlated fluorescene and AFM is suggested as a novel approach for charactizing this unique behavior.
