当空穴阻挡层为TAZ

电子传输层为Bphen时

器件的性能最优。当驱动电压为5 V时

器件最大电流效率为4.59 cd/A。在12 V时亮度最大

为6 087 cd/m

。

Abstract

Using NPBX with 3% DSA-ph doped as the emitting layer

BCP or TAZ as a hole blocking layer

Alq

or Bphen as an electron transport layer

a set of blue light-emitting devices were fabricated. A group of high efficient blue OLEDs were got by adjusting the combination between the different hole blocking layer and the electron transport layer. The result shows that when the hole blocking layer is TAZ and the electron transport layer is Bphen

the performance of the device is the best. It has a maximum current efficiency of 4.59 cd/A at 5 V and maximum brightness of 6 087 cd/m

at 12 V.
