研究了三(8-羟基喹啉)铝掺杂DCM激光染料有机半导体薄膜的激光特性与DCM浓度和环境温度的关系。与无机激光二极管相比，有机激光器的激光波长、输出功率、微分量子效率和阈值泵浦能量在0到140摄氏度的范围内与温度无关。此外，在接近160摄氏度的温度下没有观察到激光器性能的退化。[S0003-6951(97)00244-1]。
Characteristics of lasing in optically pumped, vacuum deposited organic semiconductor thin films of tris-(8-hydroxyquinoline) aluminum doped with DCM laser dye are studied as a function of DCM concentration and ambient temperature. In contrast to inorganic laser diodes, the lasing wavelength, output power, differential quantum efficiency, and threshold pump energy of organic lasers are found to be independent of temperature in the range from 0 to 140 degrees C. In addition, no degradation in laser performance was observed at temperatures approaching 160 degrees C. (C) 1997 American Institute of Physics. [S0003-6951(97)00244-1].
