摘要：

Recombination dynamics of dense excitonic systems in CdxZn1-xS-ZnS quantum-well structures has been studied by means of time-resolved luminescence spectroscopy. Experimental evidence for biexciton formation was obtained. Furthermore, ultraviolet stimulated emission was observed just at the energy position of the biexciton luminescence. It was proposed that the stimulated emission was due to the biexciton decay process. (C) 1997 American Institute of Physics.
