一种瀑布载流子俘获结构有机发光二极管的制造方法
摘要：
本发明属于一种瀑布载流子俘获结构有机发光二极管及其制造方法。掺杂层选择两种不同的有机荧光染料，同时掺杂到主体材料8－羟基喹啉铝中，三者的重量百分比为：0.2％－5％∶0.2－5％∶1，制备成结构为ITO/NPB/掺杂层/Alq3/LiF/Al的有机发光器件。两种有机荧光染料及主体材料两两之间存在较好的载流子俘获过程。利用瀑布载流子俘获原理，改善了有机发光二极管的电致发光性能，用这种方法制备的有机发光二极管具有效率高、亮度大和光谱色纯度好的特点。
摘要（英）：

Two different organic fluorescent dyes are selected as doping materials to be adulterate into 8-aluminum hydroxy quinoline. Their weight percent is as 0.2%-5%:0.2-5%:1. Alq3/LiF/Al organic light emitting device is prepared with ITO/NPB doping layer. Carrier capture process is existed between organic fluorescent dyes and between each fluorescent dye and material of main body. Electroluminescence capability of organic LED is improved by using capture principle of waterfall carrier. Organic LED prepared by using the disclosed method possesses features of high efficiency, large brightness and good spectral color purity.
