摘要

随着像素尺寸的不断缩小，传统的显示设备已无法满足日益增长的需求。因此，一种新型发光器件备受关注。这种器件在交流（AC）电场下发光，并利用绝缘层阻止外部载流子的注入。但同时，这种方法也导致亮度降低。在本文中，我们在 PEDOT:PSS 中加入了不同尺寸的金氧化物，从而实现了交流驱动 QLED 的性能提升。我们的研究发现，尺寸越大的金氮化物亮度越高，从 5512 cd/m2 上升到 7234 cd/m2，大幅提高了约 31.2%。这证明了 "远场 "效应在交流驱动 QLED 中的巨大潜力。

AC-driven QLED based on far-field effect of Au NPs

As the pixel size continues to shrink, conventional display devices are unable to satisfy the increasing demand. Therefore, a novel light-emitting device has garnered significant attention. This device emitted light under an alternating current (AC) electric field and blocked the injection of external carriers by using the insulating layer. However, at the same time, this approach leads to a reduction in brightness. In this paper, we have realized the performance enhancement of AC-driven QLEDs by incorporating Au NPs of different sizes in PEDOT:PSS. Our investigation reveals that Au NPs of greater size exhibit a notable enhancement of the brightness, rising from 5512 cd/m² to 7234 cd/m², representing a substantial increase of approximately 31.2 %. It demonstrates the great potential of the "far-field" effect in AC-driven QLEDs.
