摘要: The effects on the luminescence lineshape of spatial and temporal inhomogeneities electron-hole plasma generated by strong laser pulses in GaAs/AlGaAs multiple quantum well structures are experimentally investigated. It is found that strongly affect spectra must be taken into account for a correct interpretation experimental data. analysed using statistical model includes, simple way, used excitation. A fair agreement obtained with data; at same time values fit parameters turn out to rather sensitive assumed describing inhomogeneities. Therefore, caution has when inferring properties, such as carrier density temperature, from analysis.
