稀土镨配合物的荧光特性

The Fluorescence Properties of Praseodymium Complex

稀土配合物的光学特性与配合物的组成,价键结构和配体性质等密切相关,配体的性质对配合物的发光具有很大影响.不同配体与不同的稀土离子合成的配合物,其发光性质有时会相差很大.合成了氯化镨、咪唑、氨基酸的三元配合物,通过元素分析确定了配合物的化学式,通过红外光谱对其结构进行了表征,用OPO激光作为激发光源,观察了标题配合物和配体在不同激发波长下的荧光光谱,讨论和分析了标题配合物的荧光特性,以期探索优质的稀土发光材料.

The optical character of rare earth complexes is closely related with its composition,valence-bond structure and properties of ligands has great influence on optical characteristics of compounds.Optical property of compounds of different ligands and rare-earth ions sometimes shows great disparity.In this study,the ternary complex of praseodymium chloride with alanine and imidazole are synthesized.The chemical formula of this complex is determined by elemental analysis,its properties are represented by IR.In order to find better luminescent material,the fluorescence spectra of complex and ligands are observed with OPO laser.We also make a discussion of the fluorescent property and luminescence mechanism of complex.
