摘要
人们对有机发光二极管(OLED)的兴趣与日俱增,这在很大程度上归功于三氧化钼(MoO3)性能的显著提高。本研究旨在通过使用由银纳米线(Ag NWs)和银纳米粒子(Ag NPs)以及聚(3,4-亚乙二氧基噻吩):聚(苯乙烯磺酸)(PEDOT:PSS)和氧化钼量子点(QDs)组成的共掺杂系统,实现柔性透明电极(FTEs)和空穴注入层(HILs)的集成。这项拟议技术的主要目的是使用 MoO3 QD 作为柔性电极的一部分,减少传统器件制备过程中的 HIL 沉积步骤,从而简化柔性器件的制造。MoO3 被还原成 MoOX,为空穴注入提供了另一种途径,从而提高了载流子迁移率,进一步增强了柔性器件的性能。制备出的柔性有机发光二极管的亮度保持在原始水平的 90%,即使在经历了 500 次弯曲测试后也是如此。这些研究结果表明,将所制备的 FTE 与 HIL 集成到该系统中,可实现出色的光电性能和高机械稳定性。此外,与传统器件相比,通过减少 HIL 沉积工艺,优化了具有更高性能的柔性器件的结构。
Flexible OLED Performance Enhancement: The Impact of Ag NWs: Ag NPs Electrode-Integrated MoOX QDs Hole-Injection Layer.
The growing interest in organic light-emitting diodes (OLEDs) has largely been attributed to significant performance enhancements achieved with molybdenum trioxide (MoO3). This study aims to achieve the integration of flexible transparent electrodes (FTEs) and hole-injection layers (HILs) through the use of a codoped system comprised of silver nanowires (Ag NWs) and silver nanoparticles (Ag NPs), as well as poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) and molybdenum oxide quantum dots (QDs). The primary objective of this proposed technique is to use a MoO3 QD as part of a flexible electrode, reducing the step of HIL deposition in the traditional device preparation process, thereby simplifying the fabrication of flexible devices. MoO3 was reduced to MoOX, which offered an alternative pathway for hole injection to increase carrier mobility, thereby further enhancing flexible device performance. The luminance of the prepared flexible OLEDs remained at 90% of their original level, even after undergoing 500 bending tests. These findings indicate the fabricated FTEs, integrated into this system with HILs, exhibited excellent optoelectronic performance and high mechanical stability. Moreover, the structure of the flexible device with higher performance was optimized by reducing the HIL deposition process compared to traditional devices.
