We present a temperature-dependence photoluminescence of (GaAs)5/(AlAs)5 superlattice grown on (311)A-oriented semi-insulating substrate by molecular beam epitaxy. The temperature dependence reveals an anomalous decrease of the PL width, which is explained in terms of phonon-assisted thermal activation of localized excitons. q 2004 Elsevier Ltd.
