Rezumat

The kinetics of a strongly nonequilibrium state of electrons and holes excited in quantum dots by a long laser pulse in the p-states are studied using time-resolved photoluminescence. Three bands of the transient photoluminescence spectra are identified, and the ignition and decay of each of them is studied. The complex picture of the time evolution of the bands is attributed to the fast processes of cascade intraband relaxation and the Pauli Exclusion Principle. The durations of the formation and decay for each of the photoluminescence bands are determined.
