In this paper, we report our numerical study on the electrical and optical properties in HTL/mCP/ETL multilayer organic light emitting diode (OLED) device structure. Our finite element method (FEM) model includes the transport behavior of electrons and holes, the generation and decay of excitons, and emission and extinction properties of excitons. We employ the multilayer structure which consists of 1,1-bis[(di-4-tolylamino)phenyl] cyclohexane (TAPC); 4,4'-bis[N-(1-naphthyl)-N-phenyl-amino]biphenyl (α-NPD); 4,4'-bis[N-(p-tolyl)-N-phenylamino] biphenyl (TPD); 3,5'-N,N'-dicarbazole-benzene (mCP); 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP); 4,7-diphenyl-1, 10-phenanthroline (BPhen). We report our observation of the effect of the different hole transport layer following TAPC, α-NPD, TPD and also discuss the effect of different electron transport layer following BCP, BPhen. Our simulation revealed that the charge balance results in a significant effect on the recombination density which is related to the generation of excitons.
在本文中，我们报告了对HTL/mCP/ETL多层有机发光二极管（OLED）器件结构中的电学和光学性质的数值研究。我们的有限元方法（FEM）模型包括电子和空穴的传输行为、激子的产生和衰减以及激子的发射和湮灭特性。我们采用了由1,1-双[(二-4-甲苯基氨基)苯基]环己烷（TAPC）、4,4'-双[N-(1-萘基)-N-苯基氨基]联苯（α-NPD）、4,4'-双[N-(对甲苯基)-N-苯基氨基]联苯（TPD）、3,5'-N,N'-二咔唑苯（mCP）、2,9-二甲基-4,7-二苯基-1,10-菲咯啉（BCP）、4,7-二苯基-1,10-菲咯啉（BPhen）组成的多层结构。我们报告了对TAPC、α-NPD、TPD之后不同空穴传输层的影响的观察结果，并讨论了BCP、BPhen之后不同电子传输层的影响。我们的模拟表明电荷平衡对与激子产生相关的复合密度有显著影响。
