During the radiative decay of singlet excitons in polymer light-emitting diodes (PLEDs), the newly developed molecule dynamics not only describes the evolution of the lattice distortion of the polymer chain but also illustrates the time-dependent electron transitions and electron populations in detail. Furthermore, based on this method, it is revealed that the nonemissive triplet excitons in PLEDs become emissive through the fusion of injected positive polarons. The obtained maximum quantum efficiency is consistent with recent experimental results.
在聚合物发光二极管（PLED）中，单重激子辐射衰变过程中，新发展的分子动力学不仅描述了聚合物链的晶格畸变的演变，而且详细说明了电子跃迁和电子布居的时间依赖性。此外，基于这种方法，揭示了 PLED 中无辐射三重态激子通过注入正极化子的融合而变为辐射的。获得的最大量子效率与最近的实验结果一致。
