The decay of indirect exciton luminescence in Cdl. crystals mixed with CdBrz hasbeen measured following pulsed excitation at low temperatures. Three exponentialdecay components are observed. The intensity distribution among them varies withtemperature as well as with Br -concentration. The time-resolved measurement ofthe emission spectra suggests that the emission of the slow decay componentoriginates from a shallow bound state of an exciton located below the free state. Thedecay characteristics and the temperature dependence of the emission efficiency are ac-counted for in terms of changing populations in both the free and bound states. Theresult of analysis indicates that the potential barrier between the free and the self-trap-ped exciton states is lifted by the mixing of CdBr..
