摘　　要：白光有机电致发光器件(white organic light emitting diodes,WOLEDs)在显示和照明领域有着极大的应用前景,受到人们的广泛关注。基于荧光和磷光复合发光的WOLEDs结合了荧光器件与磷光器件的优点,提供了实现高效白光器件的新思路。本文按小分子和聚合物器件分类综述了近年来荧光磷光复合发光白光器件的研究进展,对器件结构、荧光磷光之间的能量传递与发光机理等方面进行了讨论,并对此类器件未来的研究方向进行了展望。White organic light emitting diodes （WOLEDs） have been attracting considerable attention due to their potential applications in large-area flat panel displays and solid-state light sources. In recent years, many highly efficient WOLEDs with various structures have been fabricated by combination of fluorescence and phosphorescence because this method can combine the merits of fluorescent and phosphorescent devices. In this paper, recent progress of this kind of WOLEDs is reviewed with a view to the materials, device structure and light emitting mechanism. Some issues to be addressed and orientations to be further studied are also put forward and discussed.
