Abstract

With the development of experimental techniques, effective injection and transportation of electrons is proven as a way to obtain polymer light-emitting diodes (PLEDs) with high quantum efficiency. This paper reveals a valid mechanism for the enhancement of quantum efficiency in PLEDs. When an external electric field is applied, the interaction between a negative polaron and triplet exciton leads to an electronic two-transition process, which induces the exciton to emit light and thus improve the emission efficiency of PLEDs.

摘要

随着实验技术的发展，电子的有效注入和传输被证明是获得具有高量子效率的聚合物发光二极管（PLED）的一种方法。本文揭示了一种提高PLED量子效率的有效机制。当施加外部电场时，负极化子与三重态激子之间的相互作用导致电子双跃迁过程，这会诱导激子发光，从而提高PLED的发光效率。
