稀土有机电致发光材料

Rare Earth Complexes as Electroluminescent Materials

有机电致发光 (OEL)是目前国际上一个热点研究课题 ,稀土配合物发光的色纯度高 ,作为OEL材料具有独特的意义。本文介绍了稀土OEL材料的发光机理 ;讨论了稀土OEL材料的结构(包括配体、第二配体和中心离子 )对其发光特性的影响 ,以及材料的电致发光性能与光致发光性能的关系。

The organic electroluminescence (OEL) is a hot spot of current research topics in the world. The rare earth complexes as OEL materials possess unique significance because of the high colour purity of their luminescence. In this paper, the luminescence mechanism of the rare earth complexes as OEL materials was introduced. The effect of structure (including ligands, second ligands and central ions) of the rare earth complexes as OEL materials on the luminescent properties and the relation between the electroluminescent performance and the photoluminescent performance of the materials were discussed.
