摘要

通过采用毫米尺度的凹凸界面结构实现了有机发光器件（Organic Light Emitting Device，OLED）发光效率的提高。在制备OLED器件过程中使用双狭缝模板，在发光层的界面处构建了高度为10 nm的凸起，获得最大功率效率为23.9 lm/W，最大电流效率为45.6 cd/A，与传统的平直界面的OLED相比，分别提高了70%和36%。经过实验数据分析与理论模拟得出初步结论：OLED发光效率提高主要归因于金属界面处局域表面等离子体共振激发，提高了金属阴极界面的远场散射，从而提高OLED的出光效率；另外适当凹凸深度也改善了器件的电学性能。

Abstract

High electroluminescence intensity based organic light emitting diodes (OLEDs) with millimeter-scale concavo-convex interface were addressed. Using template with double-slits up to 10 nm-height-protrusion

a maximum power and current efficiency of 23.9 lm/W and 45.6 cd/A were achieved

enhancing 70% and 36% compared with the optimized general planar device structure

respectively. The enhancement in luminescence intensity can mainly be attributed to the localized sur face plasmons (LSPs) induced by the metallic corner because the effective scattering of the LSP-metallic corner would result in enhancement in light extraction efficiency. More detail enhancement mechanism of the EL intensity was also argued.
