摘要

以水溶性酞菁铜(CuTcPc)为空穴注入层制备多层有机电致发光器件。ITO表面经过CuTcPc溶液修饰

能够提高空穴的注入能力

增加器件的电流密度和亮度。在有机电致发光器件中

空穴传输材料的空穴迁移率一般大于电子传输材料的电子迁移率

空穴是多数载流子;但是

CuTcPc修饰处理不仅提高了器件的电流密度和亮度

也提高了器件的电流效率。研究结果表明

CuTcPc层不仅提高了器件的空穴注入能力

也影响了电场的分布

能在一定程度上增加电子的注入。

Abstract

OLEDs with configurations of ITO/CuTcPc/NPB/Alq

∶C545T/Alq

/LiF/Al

ITO/CuTcPc/NPB/Alq

∶C545T/Alq

/Al were fabricated using CuTcPc as electron injection layer

NPB as hole transport

layer Alq

∶C545T as emission layer

and Alq

as hole transport layer. In our experiments

the CuTcPc treated devices have greater luminances than that of the conventional devices. As holes are the majority carriers in these multilayer OLEDs

the increased hole injection should lead an imbalance of carrier and a lower efficiency. But through our experiment

it is found that both the hole injection and the electron injection are increased after CuTcPc surface treatment. CuTcPc surface treatment can not only improve the luminances and the current density

but also can improve the current efficiency of the devices comparing with the conventional devices.
