摘要：

The behaviour of the cooperative emission from PbI2 and HgI2 at 80 K has been studied at high exciton density by means of a tunable high intensity dye laser pumping. From a comparative analysis of the observed M and S stimulated emission lines from PbI2 and HgI2 we find that they strongly depend in two different ways on the pumping photon energy. Then, it is also possible to conclude that exciton-exciton and exciton-electron inelastic scattering are responsible for stimulated emission in PbI2 and HgI2 respectively. © 1979.
