摘要

采用碳酸锂(Li

)为n型掺杂剂

苝四甲酸二酐(3

10 perylenetetracarboxylic dianhydride

PTCDA)为母体材料

通过真空热蒸发方式制备了n型掺杂的PTCDA复合材料

将其作为电子注入材料应用到NPB/Alq

异质结有机电致发光器件中。研究发现

同Li

∶ BCP(1 ∶ 4)/Al 结构和LiF/Al结构相比

∶ PTCDA(1 ∶ 1)/Al结构能显著提高发光器件的亮度

器件功率效率也有所增加。发光器件性能的提高可以归因于两点:一是Li

∶ PTCDA(1 ∶ 1)的电导率显著高于Li

∶ BCP(1 ∶ 4)和本征Alq

能够有效降低电流传导过程中的欧姆损失;二是阴极Al原子的渗透使Alq

/Li

∶ PTCDA界面变成欧姆接触。

Abstract

Lithium carbonate doped 3

10-perylenetetracarboxylic dianhydride (Li

∶ PTCDA) was fabricated as electron injection layer in NPB/Alq

heterojunction based organic light emitting diodes (OLEDs). It was found that the current of OLED using Li

∶ PTCDA was strongly dependent on the Li

doping concentration. The OLED using Li

∶ PTCDA(1 ∶ 1) with Al as the cathode exhibits an improved power efficiency and significantly increased luminance

comparing with the one using Li

∶ BCP(1 ∶ 4) with Al as the cathode and the one using the regular LiF/Al cathode.It is because the electron conductivity for Li

∶ PTCDA/(1 ∶ 1) is much higher than that Li

∶ BCP(1 ∶ 4) and neat Alq

. In addition

it is found that there exist a Schottky barrier at the intrinsic interface of Alq

and Li

∶ PTCDA(1 ∶ 1)

which suppress the electron transfer from Li

∶ PTCDA(1 ∶ 1) into Alq

. However

the release of Li atoms upon the Al deposition onto 1 ∶ 1 Li

∶ PTCDA could turn the interface into an ohmic contact

thereby delivering efficient electron injection from Li

∶ PTCDA(1 ∶ 1) into Alq

. We provided a class of high-function

low-cost

and easily fabricated n-doped material for the performance enhancement of OLEDs.
