title = "Photoluminescence upconversion study of GaN nanowires: Potential for optical refrigeration",
abstract = "Up-converted photoluminescence of GaN nanowires is observed at the temperature above 375 K. At 475 K, the mechanism of the photoluminescence was identified as phonon-assisted bandtail emission. Such a phenomenon contributes to optical refrigeration.",
