The results show that the response speed of OLED is significantly related to its emitting layer, light-emitting area and preset direct current voltage bias. The response speed can be improved by doping rubrene in Alq 3 emitting layer with shorter fluorescence lifetime. And 100 Mbit/s of the transmission speed has been realized from OLED with a 0.02 mm 2 of light-emitting area. Finally, flexible OLED combined with organic polymeric waveguide and organic photoelectric diode has been proposed to realizing the organic photoelectron system. 有机发光二极管 光通信 光互连 响应速度 光电转换 optical communications organic light emitting diode photoelectron response speed photoelectric conversion Nakayama T, Hiyama K, Furukawa K, et al.
