我们展示了一种观察和分析有机薄膜中的光激发分子态和电荷载流子的动力学的方法，通过同时测量瞬态光致发光和光电导。我们的实验表明，在三-（8-羟基喹啉）铝（Alq（3））的激子-激子湮灭决定的行为的光致发光和光电导在高激发强度。基于激子-激子湮没模型的计算证实了实验结果。(C)1996年美国物理学会。
We demonstrate a method for observing and analyzing the dynamics of photoexcited molecular states and charge carriers in organic thin films, by measuring simultaneously the transient photoluminescence and photoconductivity. We show experimentally in tris-(8-hydroxyquinoline) aluminum (Alq(3)) that exciton-exciton annihilation dictates the behavior of the photoluminescence and photoconductivity at high excitation intensities. The experimental results are corroborated by calculations based on an exciton-exciton annihilation model. (C) 1996 American Institute of Physics.
