摘要

设计了基于Bphen∶LiF、Al和MoO

的杂化电荷注入层，并将其应用于有机电致发光器件中。实验研究表明，这种杂化层作为阳极修饰层是非常有效的，它可以增加器件中载流子注入的平衡性，提高器件的性能。相对参考器件，基于杂化阳极修饰层的电致发光器件的最大电流效率和最大功率效率均提高1.3倍左右。我们对器件性能及其提高的机理进行了分析。

Abstract

We report the incorporation of lithium fluoride doped 4

7-diphenyl-1

10-phenanthroline (Bphen LiF)

and molybdenum trioxide (MoO

) which is utilized to form the charge injection buffer layer in single-unit organic light-emitting devices (OLEDs). This hybrid buffer layer at the anode/organic interface was found to be very effective

which increased accumulation of holes at the NPB-buffer interface to improve the balance of the carrier injection. Both the maximum current efficiency and maximum power efficiency of the device were improved by 1.3 times. The results strongly indicate that carrier injection ability and balance shows a key significance in device performance.
