摘要：

Fluorescence spectra under various excitation and detection conditions are put forward to probe exciton spectral dynamics, resulting from hopping of excitons over localized states. We address the complexity of the exciton spectral dynamics, which is a direct consequence of the interplay of localization, intra-band relaxation and radiative relaxation of excitons.
