摘　　要：本文对光致发光稀土铕配合物-聚乙烯吡咯烷酮(PVP)复合薄膜的发光性质进行了初步研究。实验结果表明,高分子材料不仅仅起到固定稀土离子,增强其发光强度的作用,而且配合物中的水分子还可以被聚合物配体所取代,避免水分子对中心稀土离子的猝灭作用。以上这些作用大大增强了配合物的发光强度,获得较高稀土配合物含量的发光薄膜,为稀土荧光物质的成膜与加工提供实验依据。The luminescence properties of photoluminescence rare earth europium complexes - polyvinylpyrrolidone .（PVP） have been studied. The experimental results show that polymer materials can not only fix rare earth ions to enhance its luminescence intensity, but also avoid the quenching effect to rare earth caused by water molecule, through the replacement of polymer ligand to water molecule in the complex. The luminescence intensity of the complex can be greatly enhanced, and the luminescence film contained high amount of rare earth complexes is obtained. So it can provide experimental basis for the film forming and processing of rare earth fluorescent materials.
