摘　　要：白光有机电致发光器件(WOLED)具备很多天然的技术优点,可以应用在下一代照明设备上,因此正成为研究的新热点.但是由于传统的多层或单层WOLED结构受染料浓度和载流子传输难以控制等因素的限制,使进一步优化器件效率和白光色度稳定成为WOLED发展的瓶颈.本工作针对传统WOLED存在的上述问题,设计制备了新型的具有颜色互补的黄色和蓝色发光条纹,交替排列所组成的WOLED器件,并且分析了黄光—蓝光条纹尺寸和改变照射角度对器件光照稳定性的影响.White organic light-emitting devices （WOLEDs） have a few technical merits for lighting application. Generally, doping-concentration and carriers-transporting effect inherent in traditional WOLEDs, however, complicate the optimization of device efficiency and color-stability characteristics. In this paper, we design and fabricate a novel WOLED concept,in which an alternant yellow and blue lighting stripe structure is used. We analyze the emission characteristic of this alternate stripe WOLED （AS-WOLED） as a function of yellow and blue stripe size and lighting angle. From the comprehensive analysis, trend in the dependence of emission characteristic on device structure is extracted, and accordingly, a general method for optimizing color characteristics of AS-WOLEDs is suggested.
