摘要：

Time-resolved luminescence measurements in AgBr at 1.9K and cw excitation densities up to 100 kW/cm2 reveal new emission bands with strong vibrational structure close to the free exciton. Besides the emission of excitons bound to isoelectronic I- traps two different luminescence systems are separated by making use of their different lifetime and excitation behaviour. The results are discussed in view of the electron-hole-liquid recombination recently found in the investigated spectral range. © 1979.
