Abstract
We image the micro-photoluminescence of single self-assembled chains of CdSe nanoplatelets. Some portions of a chain show collective fluorescence intermittency, with around 30 platelets blinking at the same time. This effect is explained and modelled as Förster-Resonant Energy Tranfer (FRET) funneling all the excitons from a chain portion to a single blinking quencher.
