In recent years, extensive research has been undertaken to develop fiber-shaped optoelectronic devices, because they are aesthetically pleasing, light in weight, and exhibit superior light emitting properties when compared with conventional planar analogues. In this work, we have successfully developed hollow-fiber shaped organic light emitting diodes (HF-OLED) with an exceptionally high luminance and facile color tunability. The HF-OLED device was fabricated by hierarchically depositing amorphous indium-doped tin oxide electrode on a hollow-fiber, followed by the sequential deposition of light-emitting organic layers and Al cathode. The external quantum efficiency of the HF-OLED is more than ∼2.0 times higher than that of a planar-OLED. The experimental results are in good agreement with the output of optical simulations, revealing that the use of a hollow-fiber has contributed to a ∼2.3 times improvement in light extraction efficiency. Furthermore, the color emission of a single HF-OLED device could be easily tuned from a green to yellowish-green wavelength after the injection of a super-yellow solution. The novel color tunable nature of the HF-OLED further broadens its application in the field of modern lighting and display technology.

高性能，颜色可调的纤维状有机发光二极管†
近年来，已经进行了广泛的研究以开发纤维状的光电器件，因为与常规的平面类似物相比，它们在美学上令人愉悦，重量轻并且表现出优异的发光性能。在这项工作中，我们成功开发了具有异常高的亮度和便捷的颜色可调性的中空纤维状有机发光二极管（HF-OLED）。HF-OLED器件的制造方法是，在空心纤维上分层沉积非晶铟掺杂的氧化锡电极，然后依次沉积发光有机层和Al阴极。HF-OLED的外部量子效率是平面OLED的约2.0倍以上。实验结果与光学仿真的结果非常吻合，揭示了使用中空纤维有助于将光提取效率提高约2.3倍。此外，在注入超黄溶液后，单个HF-OLED器件的颜色发射可以很容易地从绿色波长变为黄绿色波长。HF-OLED的新颖的颜色可调性进一步扩展了其在现代照明和显示技术领域中的应用。
