对几种有机／聚合物电致发光材料的能带结构进行了表征，设计了几种结构的器件，并对它们进行了性质比较．结果表明，通过各种材料间合理的能带匹配，可以获得综合性能较好的电致发光器件． Band structures of several kinds of organic / polymer electroluminescent materials were characterized, several structures of devices were designed, and their properties were compared. The results show that the electroluminescent devices with good overall performance can be obtained by reasonably matching the energy bands of various materials.
