It was shown that the ex-el scattering induces the main recombination process that yields high gain above 100 K both experimentally and theoretically. The results obtained so far concern mainly the stimulated emission, and most of the efforts are devoted to the temperature dependence of emission spectra. Only a few works are concerning the dynamics of the luminescence due to scattering.展开更多
