Abstract

Stretchable organic light-emitting diodes (SOLEDs) have been the challenging class of OLEDs as they have limited processability to fabricate a design that can withstand external deformation. Herein, we demonstrated the highly efficient top-emitting geometrical stretchable OLED (GSOLED) by incorporating the prestretched elastomer with optical adhesive film. The experimental and theoretical characterizations verified the enhancement of device efficiencies with the light extraction phenomenon brought by nanowavy corrugated structures. Furthermore, GSOLED shows stability in stretchable conditions and displays narrower emission spectrum with improved color purity. The full width at half maximum (FWHM) of 21 nm shows narrowband emission with a high current efficiency and EQE of 221 cd A−1 and 39.50%. This work marks a significant step forward, providing unprecedented insights into the factors influencing device performance in current and future material systems for stretchable organic light-emitting diodes.

利用纳米波浪结构制造高效可拉伸有机发光二极管,实现与角度无关的窄带发射
可拉伸有机发光二极管(SOLED)一直是一类具有挑战性的有机发光二极管,因为它们的加工能力有限,无法制造出能够承受外部变形的设计。在这里,我们通过将预拉伸弹性体与光学胶膜结合,展示了高效的顶部发光几何可拉伸有机发光二极管(GSOLED)。实验和理论表征验证了纳米波纹结构带来的光提取现象,从而提高了器件效率。此外,GSOLED 在可拉伸条件下表现出稳定性,并显示出更窄的发射光谱和更高的色纯度。21 nm 的半最大全宽(FWHM)显示了窄带发射,电流效率和 EQE 分别为 221 cd A-1 和 39.50%。这项工作标志着我们向前迈出了重要一步,为我们深入了解影响当前和未来可拉伸有机发光二极管材料系统器件性能的因素提供了前所未有的视角。
