Periodic aluminum-capped nanoslit arrays were produced on a polycarbonate plastic substrate by rapid hot embossing nanoimprint lithography and thermal evaporation, and they were used as a transparent window for blue-emitting polymer light-emitting diodes (PLEDs). The external quantum efficiency of blue-emitting PLEDs was enhanced by the surface plasmon polaritons of the periodic aluminum-capped nanoslit arrays. A maximum current efficiency of 4.84 cd/A was achieved for the proposed PLED, which was over 2.2 times that of the reference PLED (2.18 cd/A). These results demonstrate that periodic nanostructure can assist in the simple and low-cost fabrication of high-performance polymer optoelectronic devices.
通过快速热压纳米压印光刻和热蒸发在聚碳酸酯塑料基板上制备了周期性铝帽纳米狭缝阵列，并将其用作蓝色发光聚合物发光二极管（PLED）的透明窗口。周期性铝帽纳米狭缝阵列的表面等离激元极化子提高了蓝色发光PLED的外量子效率。所提出的PLED实现了4.84 cd/A的最大电流效率，是参考PLED（2.18 cd/A）的2.2倍以上。这些结果表明，周期性纳米结构有助于简单、低成本地制造高性能聚合物光电器件。
