Research on Doping of Organic Electroluminescent Devices

Keywords： fluorescence , phosphorescence , doping mechanism , charge trapping , doping efficiency

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.
