摘　　要：有机电致发光器件(Organic light-emitting device,OLED)因具有成本低、主动发光、驱动电压低、响应速度快、视角宽及可柔性显示等诸多优势,在平板显示及固态照明领域受到广泛关注。但无论是用作显示还是照明,色彩的应用都是不可或缺的。制备不同颜色的发光器件,除可以使用各种颜色的有机材料外,利用荧光或磷光染料掺杂也是重要的方法。同时,这种方法也可以大大提高器件的量子效率。尤其从理论上来说,磷光OLED的内量子效率可以达到100%。从OLED的掺杂原理、荧光掺杂与磷光掺杂等方面阐述了OLED的研究进展。Organic electroluminescent device （OLED） has many advantages, such as low cost, self-luminous, low driving voltage, fast response, wide viewing angle and flexible displays. It attracted widespread attention in the field of flat panel displays and solid-state lighting. No matter displaying or lighting, the application of color is indis- pensable. In addition, full-color display can be used for organic materials, and using fluorescent or phosphorescent dye doping is also an important method of preparing full-color device. At the same time, it has improved the quantum effi- ciency of the device. Especially, the internal quantum efficiency of phosphorescent OLED can reach 100%. The research progress of OLED from the OLED doping principle to fluorescent and phosphorescent doping aspects is reviewed.
