Abstract

Luminous efficiency is a pivotal factor for assessing the performance of optoelectronic devices, wherein light loss caused by diverse factors is harvested and converted into the radiative mode. In this study, we demonstrate a nanoscale vacuum photonic crystal layer (nVPCL) for light extraction enhancement. A corrugated semi-transparent electrode incorporating a periodic hollow-structure array was designed through a simulation that utilizes finite-difference time-domain computational analysis. The corrugated profile, stemming from the periodic hollow structure, was fabricated using laser interference lithography, which allows the precise engineering of various geometrical parameters by controlling the process conditions. The semi-transparent electrode consisted of a 15 nm thick Ag film, which acted as the exit mirror and induced microcavity resonance. When applied to a conventional green organic light-emitting diode (OLED) structure, the optimized nVPCL-integrated device demonstrated a 21.5% enhancement in external quantum efficiency compared to the reference device. Further, the full width at half maximum exhibited a 27.5% reduction compared to that of the reference device, demonstrating improved color purity. This study presents a novel approach by applying a hybrid thin film electrode design to optoelectronic devices to enhance optical efficiency and color purity.

摘要

发光效率是评估光电器件性能的关键因素，其中由各种因素引起的光损失被收集并转换为辐射模式。在本研究中，我们展示了一种用于增强光提取的纳米级真空光子晶体层（nVPCL）。通过利用时域有限差分计算分析的模拟，设计了一种包含周期性空心结构阵列的波纹状半透明电极。源于周期性空心结构的波纹轮廓是使用激光干涉光刻技术制造的，通过控制工艺条件可以精确设计各种几何参数。半透明电极由一层15纳米厚的银膜组成，该银膜充当出射镜并引发微腔共振。当应用于传统的绿色有机发光二极管（OLED）结构时，与参考器件相比，优化后的集成nVPCL的器件的外量子效率提高了21.5%。此外，半高宽与参考器件相比降低了27.5%，表明色纯度得到了改善。本研究通过将混合薄膜电极设计应用于光电器件，提出了一种提高光学效率和色纯度的新方法。
