摘要：

Temperature-induced luminescence was observed from uranyl nitrate hexahydrate crystals. Flashes of green light were detected when the crystal was cooled with liquid nitrogen and also when the cooled crystal was allowed to return to room temperature. They mostly occurred between 77 and 100 K. More and stronger flashes were observed during cooling. The intensities of these flashes and the temperatures of the crystal were recorded and plotted. The intensity-temperature plots were different for the cooling and warming cycles of the same crystal and other crystals. The characteristics of the temperature-induced luminescence were compared to those of fluorescence and triboluminescence. (C) 2001 Elsevier Science Ltd. All rights reserved.
