ABSTRACT
It has been more than 10 years since the seminal paper of Bawendi et al. [1] on the resonantly excited photoluminescence (PL) in CdSe nanocrystals (NCs). This first investigation showed that in the case of resonant excitation, the PL from CdSe NCs shows a fine structure that is Stokes shifted relative to the lowest absorption band. The fine-structure PL consists of a zero-phonon line (ZPL) and longitudinal optical (LO) phonon satellites. The lifetime of PL at low temperatures is extremely long, on the order of 1000 ns. All of the major properties of the resonant PL in CdSe NCs have been described using the dark/bright-exciton model [2,3].
