| 摘 要： | 有机发光二极管(organic light emitting diode, OLED)具有重量轻、功耗低、 响应时间快及具有柔性等特点,在平板显示 及固态照明等方面均显现出巨大的优势。为进一步提高OLED器件性能,本文利用ExpertOLED 仿真软 件对具有不同光栅结构的实际OLED器件进行仿真模拟,分析不同结构的微纳光栅对双金属电 极OLED 器件电致发光((electroluminescent,EL)光谱、发光视角及器件内部电场强度分布的影响。通过优化,得到增强 器件发光强度 和拓宽发光视角的微纳光栅结构。在不同的光栅周期下,改变光栅高度对器件的发光性能有 不同的影响。 调节发光层中分子偶极取向,优化器件内部电场强度分布,可进一步对器件的发光性能进行 优化,从而为实验上利用周期性微纳光栅结构提高OLED器件性能提供了具有价值的参考。

| Abstract: | Organic light emitting diode (OLED) devices possess the characteristic s of light weight,low power consumption,high response speed and flexibility.They have shown the grea t superiority in the flat panel display and solid-state lighting.In order to enhance the performanc e of OLED devices,the Expert OLED software was used to simulate the actual OLED devices with different grating structures. The electroluminescent (EL) spectrum,the luminous angle and the electric field distribution were analyzed in the OLED devices with bimetal electrodes.The optimized micro/nano grating structures was obtained.And for OLEDs with different grating periods,the varied grating h eight has different effects on the luminescence performance.We can also improve the luminescence pe rformance by adjusting the molecular dipole orientation of emitting layer and optimizing the electric field distribution in the OLEDs.This work provides a valuable reference on improving the performan ce of OLEDs by using the optimized periodic micro/nano grating structures. |
