制作了HAT-CN作为空穴注入层的蓝、黄二基色分离的堆叠式高效有机发光二极管,器件结构为:ITO/2-TNATA或HAT-CN(x nm)/NPB(25 nm)/ADN(30 nm):TBPE (2％):DCJTB (1％)/Alq3 (20nm)/LiF(1 nm)/Al(100 nm).实验结果表明,HAT-CN对载流子的注入和色纯度的影响很明显.相比于传统器件将CuPc和2-TNATA作为空穴注入层,HAT-CN作为空穴注入层得到了更高的效率和色纯度,CIE 色坐标x=0.3309,y=0.3472,电流效率达到6.4 cd/A.

This paper investigated a high efficiency stacked white fluorescent organic lightemitting diodes consisting of separate blue and yellow elements with a 1,4,5,8,9,11-hexaazatriphenylene-hexacar bonitril (HAT-CN) hole injection layer.The configurations of the devices are ITO/2-TNATA or HAT-CN(x nm)/NPB (25 nm)/ADN (30 nm):TBPE (2％):DCJTB(1％)/Alq3(20 nm)/LiF (1 nm)/Al (100 nm).According to the experimental result,the effect of HAT-CN film on carrier injection and color purity were significant.This work obtained a higher efficiency and color purity for the WOLED with HAT-CN layer,as compared to the conventional devices with copper phthalocyanine (CuPc) or 2-TNATA materials as a hole injection layer.It shows pure-white light emitting with 1931 CIE chromaticity coordinates x=0.3309,y=0.3472,and a current efficiency of 6.4 cd/A.
