摘要

提出了一种非掺杂式电荷生成层:LiF/Al/C

-MTDATA

以其制作的叠层有机电致发光器件的最大电流效率和功率效率达到48.4 cd/A和19.4 lm/W

分别是单层发光器件的2.95倍和1.65倍。通过设计一系列含不同电荷生成层的倒置型器件

证实了电荷的生成和分离作用均发生在C

-MTDATA界面

同时通过对C

和Al的厚度以及Al蒸镀速率的研究

揭示了电荷生成和分离机制。

Abstract

A new kind of charge generation layer (CGL) without doping: LiF/Al/C

-MTDATA was reported in this work

and a series of tandem OLED(TOLED) were fabricated using this new CGL. The TOLED offered a max current-efficiency of 48.4 cd/A and a power-efficiency of 19.4 lm/W

respectively

which increased by 2.95 and 1.65 times compared with the reference device. We also constructed a series of reversed devices with several CGLs

and by exploring the effect of the thicknesses of C

and Al films and the evaporating ratio of Al on the new CGL

charge generation and dissociation mechanism in the CGL were made clear.
