The dynamic spectral characteristics of close-packed quantum dots excited by a ∼ 30 ps laser pulse in a film formed by drop casting from a toluene solution were studied. Information on the dynamics of single-exciton photoluminescence and amplified spontaneous radiation was obtained from the time-resolved PL spectrogram of the QD thin film. Amplified spontaneous radiation was observed by excitation by a “long” pulse.
Keywords: quantum dot, photoluminescence, exciton, biexciton, amplified spontaneous luminescence.
