含稀土铕配合物的PVP薄膜的制备及发光性质

Study on Preparation of PVP Film with Rare Earth Europium Complex and Its Luminescent Properties

制备了含有稀土配合物Eu(TTA)3.3H2O和Eu(TTA)3phen.H2O的高分子基质材料聚乙烯吡咯烷酮(PVP)复合薄膜,通过元素分析、红外光谱、紫外光谱和荧光光谱的测试,确定了配合物的组成及结构,研究其荧光性质。实验结果表明:在制得的PVP薄膜中稀土铕的有机配合物含量较高,且具有非常优良的发光性能。

The PVP composite film containing the Eu（TTA） 3 3 H2 O and Eu（TTA） s phen H2 O was synthesized. The composition and structure of the complex was ascertained with elemental analysis, IR and UV spectrograph study. Moreover, the fluorescence characteristic of the complex was studied by fluorescent spectrum. The results show that the content of the rare earth europium complex contained in the PVP composite film is much higher and it is of better optical performance.
