摘要：
The dynamic and spectral characteristics of close-packed quantum dots excited by a -30 ps long laser pulse in a film prepared by a drop casting method from toluene solution were investigated. The photoluminescence wavelength of single excitons and the wavelength of amplified spontaneous radiation associated with a stimulated decay of biexcitons were obtained. From the spectrogram of the time-resolved photoluminescence the information was obtained about the dynamics of these two types of radiation. It was shown that the radiation peak maximum of single excitons appears by 60 ps later than the maximum of amplified spontaneous radiation, then it slowly becomes narrower and diminishes. The amplified spontaneous radiation lasts for 200 ps.
