摘要

使用真空热蒸镀法制备的OLED器件

利用不同厚度的PrF

作阳极缓冲层

并和未加缓冲层的器件进行了对比。实验结果表明: 0.5 nm厚的PrF

阳极缓冲层可以有效增强OLED器件的空穴注入能力

增强电子和空穴的浓度平衡

优化器件的电致发光特性。器件的最大电流效率为4.9 cd/A

分别是未加入缓冲层的常规器件(3.7 cd/A

最大亮度为12 230 cd/m

)的1.3倍和2.75倍。

Abstract

A high efficiency organic light emitting device (OLED) was fabricated by a facile way based on an ultra thin praseodymium fluoride (PrF

) as the anode buffer layer. The PrF

anode buffer layer device shows some dramatic properties such as higher hole injection

stable and high current efficiency

and much higher luminance compared with those of the traditional ITO anode device. The 0.5 nm PrF

anode buffer layer device gives the maximum current efficiency and luminance of 4.9 cd/A and 33 600 cd/m

respectively

comparing with the traditional ITO anode device of 3.7 cd/A and 12 320 cd/m

. The reason of the optimized device was also discussed.
