Abstract
The cooling of a hot photoexcited exciton distribution in wurtzite GaN is studied by time-resolved photoluminescence measurements on the longitudinal optical phonon replicas of the free exciton. The temperature of the excitons decreases for sample temperatures below 60 K within 150 ps down to the lattice temperature. The transient temperature is theoretically described in terms of exciton-phonon scattering via an acoustic deformation potential of 13 eV.
