摘要
提出了一种利用Ag/Al电极作为叠层结构的连接层,有效调控白色有机电致发光器件(WOLEDs)的发射光谱和提高器件的发光效率的新方法。当连接层厚度从9nm降到5nm,白光区域内的色坐标从(0.27,0.29)变化到(0.38,0.31)。此外,通过调控任意色度的互补色(蓝黄)WOLEDs,成功地制备了色温从8009K到4539K的可以独立寻址的器件。最后,论文讨论了基于独立寻址实现色温可控的红绿蓝三基色WOLEDs的光电性能。
This paper proposes a novel method to control the emission spectrum of the white organic light-emitting devices (WOLEDs) and improve the device efficiency, which uses A1/Ag as an interconnect layer of the stacked WOLEDs. When the interconnection layer decreases to 5 nm from 9 nm, the Commission Internationale de I' Eclairage coordinates change to (0.38, 0.31) from (0.27, 0.29) within the white-light region. Moreover, we have successfully achieved the complementary WOLEDs (blue and orange) with the desired color temperature (CT), which varies from 8009 K to 4539 K, demonstrating that the CT can be regulated by individual cells. Finally, the paper discusses the optical-electrical characteristics of CT-controllable RGB WOLEDs based on individually addressable method.
