Abstract:
A physical model is proposed for a single CdSe nanocrystal coated with a ZnS shell which can explain the power-law statistics of its experimentally observed intermittent photoluminescence. If the localized electron-hole pairs (excitons) form in the nanocrystal, this suggestion alone will suffice to explain why the on-time distribution follows the law close to t−1.5 found experimentally.
