AI 中文摘要
我们从表征三重态激子动力学的全套参数中推导出红荧烯和并四苯中双生三重态激子融合产生的荧光量子拍频的幅度。我们发现，该幅度在并四苯中取决于裂变时间，而在红荧烯中并非如此，其由三重态输运的维度决定。动力学蒙特卡罗模拟再现了两种材料中的实验数据，在并四苯中裂变时间约为200 ps且三重态输运各向同性，在红荧烯中三重态沿人字轴的跳跃时间为250 ps且输运各向异性。
英文摘要
We derive the amplitude of quantum-beats in the fluorescence from geminate triplet-exciton fusion in rubrene and tetracene from the full set of parameters that characterize triplet exciton dynamics. We find that the amplitude depends on the fission time in tetracene, but does not do so in rubrene, where it is determined by the dimensionality of triplet transport. Kinetic Monte Carlo simulations reproduce the experimental data in both materials, for a fission time of the order of 200 ps and isotropic triplet transport int tetracene, and for a triplet hopping time along the herringbone axis of 250 ps and anisotropic transport in rubrene.
