The Influence of Hole Injection Materials on Performance of OLEDs

摘要

In this paper, the influence of different anode buffer layer materials on the performance of OLEDs was studied. For the device using CuPc, 2T-NaTa and TcTa as buffer layer, the maximum luminous efficiency is 2.94 cd/A, 2.4 cd/A and 18 cd/A respectively. The threshold voltage using 2T-NaTa as buffer layer is the lowest among them. 2T-NaTa is most suitable for using as anode buffer layer.
