我们已经证明了[α，omega-二-联苯基-4-基三噻吩单晶(BP3T)][α，omega-二-联苯基-4-基三噻吩单晶(BP3T)]的单晶表现出了有趣的光子特性：(1)具有与其他优化的有机固体激光系统相当的低阈值8微焦耳/厘米(2)的自波导放大自发光发射；(2)基于晶体中的光学自限制效应的激光振荡。我们还介绍了基于双极注入的晶体的电致发光以及晶体对强电流驱动的耐受性。这些结果有力地表明，BP3T晶体是一种很有前途的有机激光二极管候选材料。(C)2005年美国物理研究所。
We have demonstrated that single crystals of a thiophene/phenylene co-oligomer [alpha, omega-bis-biphenyl-4-yl-terthiophene (BP3T)] show interesting photonic aspects: (1) the self-waveguided amplified spontaneous light emissions with a comparable low threshold of 8 mu J/cm(2) to other optimized organic solid-state laser systems, and (2) the laser oscillation based on the optical self-confinement effect in the crystals. We have also presented electroluminescence from the crystals based on bipolar injection and the crystals' tolerance for intense current driving. These achievements strongly imply that BP3T crystals are a promising candidate for organic laser diodes. (c) 2005 American Institute of Physics.
