Abstract
Fast initial decays of both the luminescence intensity and the circula r luminescence polarization at high exciton densities, under resonant excitation, are reported for the first time. These fast decays are sim ultaneously initiated by the increase of the ellipticity of the photog enerating picosecond laser beam. The theory of the mechanism illustrat es the driving role of the interexciton exchange interaction.
