摘　　要：以铟锡氧化物(ITO)玻璃基片为衬底,8-羟基喹啉锂(Liq)掺杂红荧烯(Rubrene)作为单一发光层,制备结构为ITO/PTV:TED/Liq:Rubrene/Alq_3/Al的白色有机电致发光器件(OLED),对4种不同掺杂浓度器件进行比较,分析了掺杂剂对器件发光亮度的影响,并对上述器件的发光和电学性能进行了研究和探讨.A kind of white OLED with single luminescent layer was designed, in which Rubrene was doped in Liq. The structure was ITO/PVK ： TPD/Liq ： Rubrene/Alq3/Al. Comparing with four types of white organic light-emitting devices and analyzed effects of the luminescent mechanisms of the devices by using different doping concentrations. The emitting and luminescent characteristics of the devices were also discussed.
