中文摘要：
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：1170／2-TNATA或HAT—CN（znm）／NPB（25nm）／ADN（30nm）：TBPE（2％）：DCJTB（1％）／Alq3（20nm）／LiF（1nm）／A1（100nm）。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z=0．3309，y=0．3472，电流效率达到6．4ed／A。
英文摘要：
This paper investigated a high efficiency stacked white fluorescent organic light emitting 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（χ nm）/NPB （25 nm）/ADN （30 nm） ：TBPE （2%/60） ：DCJTB（1%）/Alq3 （20 nm）/LiF （1 nm）/A1 （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 .χ=O. 330 9, v=O. 347 2, and a current efficiency of6.4cd/A
