To maximize luminescent brightness in organic light-emitting diode (OLED) systems, charge transport dynamics of emissive layer is needed to be controlled. Herein, we pattern aligned micrometer scale conjugated polymer structures using a solution based processing method. Super yellow (SY)-polyethylene oxide (PEO) nanofibers were electrospun using simple uniaxial electrospinning method. A hybrid bilayer of SY-PEO fiber and poly (9,9-dioctylfluorene) derivative PFO film was formed by the sequential deposition of the electrospun fiber and spin-coated film. The maximum brightness of hybrid LED devices was increased over 1.7 fold to that of film-film bilayer device possessing same average film thickness. Besides, optical properties such as absorption/luminescence of SY were modulated by the rapid crystallization and solvent evaporation during electrospinning process compared to the spin-coated film. The electroluminescence enhancement and color control was attributed to balanced charge transport and enhanced Förster resonance energy transfer (FRET).

为了最大化有机发光二极管（OLED）系统中的发光亮度，需要控制发射层的电荷传输动力学。在本文中，我们使用基于溶液的加工方法对对齐的微米级共轭聚合物结构进行图案化。使用简单的单轴静电纺丝方法对超黄（SY）-聚环氧乙烷（PEO）纳米纤维进行电纺。SY-PEO纤维和聚（9,9-二辛基芴）衍生物PFO膜的混合双层是通过依次沉积电纺纤维和旋涂膜而形成的。混合型LED器件的最大亮度比具有相同平均膜厚的薄膜-薄膜双层器件的最大亮度提高了1.7倍。除了，与旋涂膜相比，电纺过程中的快速结晶和溶剂蒸发可调节SY的光学特性（如SY的吸收/发光）。电致发光的增强和色彩控制归因于平衡的电荷传输和增强的Förster共振能量转移（FRET）。
