Abstract
We performed time-resolved luminescence and polarization-resolved pump-probe experiments in CdSe/ZnS nanocrystals (NCs) under low and high excitations at room temperatures. At high excitations, the PL spectra shows a red shift (0.54 meV) and two-step decay. In pump-probe experiments, we observed very fast spin-flip process (~1 ps) and population oscillation, which is attributed to the Rabi oscillation.
