摘要

研究了单层MoO

(5 nm)和复合Au(4 nm)/MoO

(5 nm)HILs对OLEDs器件性能的影响

器件结构为ITO／HIL／NPB(40 nm)／Alq

(60 nm)／LiF (1 nm)/Al (100 nm)。与单层MoO

HIL的器件相比

具有复合Au/MoO

HIL的器件具有较大的电流和亮度。这是由于Au的功函数介于ITO和MoO

之间

导致Au的引入提高了空穴的注入效率。

Abstract

OLEDs have been recognized as charge-injection electroluminescent devices. Using suitable hole injection layer (HIL) can reduce the barrier of hole injection from the anode to the hole transport layer

improve the hole injection

decrease the driving voltage of the OLEDs and enhance the efficiency and stability of the OLEDs. In this article

the OLEDs with structure of ITO／HIL／NPB(40 nm)／Alq

(60 nm)／LiF (1 nm)/Al (100 nm)

where the HIL is single MoO

(5 nm) layer or composite Au(4 nm)/MoO

(5 nm) layers

were reported. It was found that the OLEDs with the composite Au/MoO

HIL shows higher current density and luminance than those of the OLEDs with single MoO

HIL at the same driving voltage

which indicates that hole injection is improved by further introducing the 4 nm Au between ITO and MoO
