Abstract ： The ultrafast exciton trapping dynamics in ZnSe/ZnCdSe short period superlattice quantum wells has been studied by using transient photoluminescence spectroscopy. A rapid exciton trapping time of less than 7ps from the barriers to the wells is measured. In Te doped samples self-trapped excitons give rise to Stokes shifted broad band luminescence and exhibit much longer lifetime.
