The photoluminescence (PL) of ZnSe 0.92Te 0.08?ZnSe superlattice quantum wells at 77K under hydrostatic pressure up to 7.8 GPa was studied. Strong PL peaks from excitons trapped in isoelectronic traps in ZnSe 0.92Te 0.08 were observed. It was found that the pressure coefficients of the PL peaks from Te traps are about half of that of ZnSe. It demonstrates the localized characteristic of the potential of Te isoelectronic traps. The excitons transition between Te traps in ZnSe 1-xTe x and (CdSe) 1?(ZnSe) 3 superlattice was also investigated.
