Résumé     
In the quantum confinement regime, the time-resolved photoluminescence mapping of CdSe nanocrystals reveals unusual size-dependent characteristics in solute or solid-state environments. The former case typifies long-lived intradot exciton recombinations, while in the latter energy-dependent Kohlrausch relaxations quench luminescence via interdot energy transfer. The observed energy transfer rate increases for larger size (1.5 X 10(8) s(-1) for d = 2.5 nm and 6.4 X 10(8) s(-1) for d = 10 nm). (C) 2010 American Institute of Physics. [doi: 10.1063/1.3497269]
