Stimulated Photoluminescence
Part of the Lecture Notes in Physics book series (LNP, volume 57)


The photoluminescence of GaSe at high excitation intensities is reported. Four lines, whose intensity increases superlinearly with excitation, are resolved and their behaviour is investigated as function of excitation intensity, excitation frequency and temperature. According to their spectral position and their behaviour, two lines are attributed to different exciton-exciton scattering processes while the remaining two which give rise to spontaneous and stimulated emission, respectively, are tentatively attributed to exciton-carrier scattering.
