The temperature-dependent photoluminescence (PL) measurements on SQW AlGaN-based UV LEDs with a peak emission at 280 nm was performed. As such, the PL peak energy position showed an S-shaped shift as a function of temperature. From a study of the PL integrated intensity as a function of temperature, two nonradiative recombination processes were found to be involved in the thermal quenching of radiative emission.
