Y. Yamada et al., TIME-RESOLVED NONLINEAR LUMINESCENCE OF BIEXCITONS IN ZNSE-ZNXMG1-XSYSE1-Y SINGLE QUANTUM-WELLS, Physical review. B, Condensed matter, 52(4), 1995, pp. 2289-2292
Nonlinear optical properties of dense excitonic systems in ZnSe-ZnxMg1
-xSySe1-y single quantum wells have been studied by means of time-reso
lved nonlinear luminescence spectroscopy, based on an excitation corre
lation technique. The enhancement in luminescence efficiency of biexci
tons was clearly observed in a time-correlation trace of nonlinear bie
xciton luminescence. The origin of the enhancement was attributed to t
he stimulation of biexciton luminescence.
