| 摘 要： | 合成了钕-草酸-丙烯酸三元固体配合物。利用元素分析、红外光谱(FT-IR)、紫外-可见光谱(UV-Vis)、热重分析(TGA)和荧光光谱等手段研究了配合物的结构和性质。结果表明配合物的组成为Nd(OOC—COO)(CH2CH—COO)].3H2O,热分析结果表明该配合物具有较好的热稳定性。荧光光谱表明配合物都具有较好的荧光特性,且发射谱线很窄,主发射峰为钕离子的4G5/2 2G7/2-4I9/2跃迁,表明合成的新型稀土配合物可用作光致发光材料。

| Abstract: | The novel ternary solid complex of rare earth neodymium (Nd) with oxalic acid (OA) and acroleic acid (AA) was synthesized. The chemical structure and the properties of the complex were characterized by using the element analysis, FT-IR, UV-Vis spectrum, thermal gravimetric analysis (TGA) and fluorescence spectrum. Their composition was determined to be Nd(OOC-COO) (CH2CH-COO)]·3H2O. The TGA result showed that the complex has excellent thermal stability. The fluorescence spectrum suggested that the innovative complex containing rare-earth ions (Nd3+), with strong characteristic emissions due to the 4G5/2+2G7/2-4I9/2 transition of Nd3+ ions, is a kind of photoluminescence materials. |
