摘要:
本文以有机电致磷光器件ITO /NPB / CBP+Ir(ppy)3/ LiF/Al为研究对象，以CBP(4,4＇-N,N＇-二咔唑联苯)为主体材料，Ir(ppy)3（三（2-苯基吡啶）铱）为磷光掺杂剂，NPB为空穴传输层。在NPB/CBP+Ir(ppy)3界面处构成凹凸结构，对不同凹凸发光层的磷光器件NPB/CBP+Ir(ppy)3界面进行研究, 并通过电流密度-电压-亮度曲线、电流效率-电压曲线分析器件的界面电荷俘获以及注入电荷动力学，确定发光层的最佳凸起个数，当凸起个数为3个时，器件的最大电流效率为22 cd/A，与传统结构器件相比提高了26%。
Abstract:
On the basis of a traditional phosphorescent organic light emitting device (PHOLED) with the structure of of ITO / NPB / CBP+Ir ( ppy ) 3 / liF / Al , with CBP ( 4, 4 ’ - N, N ’ - two carbazole biphenyl ) as the host material, Ir (ppy) 3 ( three ( 2 - phenyl pyridine ) Iridium ) as phosphorescent dopant, NPB as a hole transport layer. Where concavo-convex shape was constructed at the NPB/CBP:Ir(ppy)3 interface, the different concave -convex emitting layer phosphorescent device of NPB / CBP+ Ir ( ppy )3interface is studied, and use the current density -voltage -brightness concavo-convex efficiency - voltage curve analysis device interface charge trapping and injected charge dynamics, determine the optimal concavo-convex number of light emitting layer, when the convex number is 3, the maximum current efficiency of this device is 22cd/A, and was 26% higher than traditional structure device.
