摘　　要：有机电致发光器件(OLED)经过近三十年的发展,已经在照明和显示上得到一定程度的应用。OLED具有全固态、响应速度快、易于实现柔性显示等优点。由于磷光材料的应用,其内量子效率几乎达到了理论的极限值100%,但其外量子效率却只有20%左右,制约外量子效率进一步提高的主要因素是器件的光取出效率。本文从提高OLED光取出效率的方法入手,综述了国内外关于顶发射和底发射有机发光器件光取出效率增强的研究现状、最新进展及以后的研究方向。Organic light emitting devices（OLEDs） have been used in flat-panel displays and lighting with a near-30-year development. OLEDs possess many advantages,such as full solid device,fast response,flexible display,and so on.As the application of phosphorescence material,the internal quantum efficiency of OLED has almost reached 100%,but its external quantum efficiency is still not very high due to the low light extraction efficiency.In this review the authors summarizes recent advances in light extraction techniques that have been developed to enhance the light extraction efficiency of OLEDs.
