We report the observation of a new trapping center in Al{sub 0.3}Ga{sub 0.7}As. The center becomes active under a hydrostatic pressure of {similar to}45 kbar, and has an unusually deep emission barrier. It quenches all radiative transitions and causes a hysteresis in the photoluminescence intensity, which we interpret via a lattice-relaxation model. It is neither the DX nor the SD center, and probably related to a donor.
