摘要
稀土元素具有独特的电子层结构,是一类丰富的发光材料宝库。将稀土配合物应用于有机电致发光显示器件(OLED)对于实现全彩色显示具有重要意义。与通常的有机电致发光显示器件相比,稀土配合物有机电致发光器件具有高色纯度发射和高内量子效率的优点。本文概述了稀土配合物分类、稀土配合物有机电致发光器件研究进展和优点,着重研究了稀土离子及其OLED器件的发光机理。
elements of rare earth have particular configurations of electronic shell, and is an abundant mine of luminescent materials. The application of rare earth complexes in organic light emitting diode （OLED） is very significative for realizing full color display. Compared to traditional OLED, organic electroluminescent device doped rare earth complexes into its emitting layer has higher color purity and inner quantum efficiency; In this paper, the classification of rare earth complexes,the development and advantages of such devices mentioned above are summarized in detail, and the luminescence principles are also studied furtherly.
