Se/ZnSe single quantum well grown by LP MOCVD was measured for different excitation intensity at 77K. The spontaneous spectra show two emission peaks at 451.5nm and 452.9nm respectively. Compared to stimulated emission spectra
we can see that the stimulated emission came from the high energy emission peak in spontaneous emission spectra. The origin of the stimulated emission was attributed to exciton exciton process in the sample.
