摘　　要：本文以稀土铕、钐(Eu、Sm)氯化物、呋喃甲酸(L)和1,10-邻菲啰啉(phen)为原料,95%乙醇为溶剂,合成了两种新型的稀土配合物([Eu(L)3 phen]2·4H 2O和[Sm(L)3 phen]2·5H 2O).通过元素分析仪和热分析仪的数据确定了配合物的组成,用红外光谱(IR)、紫外光谱(UV)表征了配体和配合物的结构,分析结果表明:配合物中的中心离子Eu 3+和Sm 3+与呋喃甲酸(L)中的O原子进行了配位,同时,1,10-邻菲啰啉(phen)中N原子与Eu 3+和Sm 3+配位成功.常温下,荧光光谱仪测出两种配合物中的Eu 3+和Sm 3+均发射出本身的特征荧光,这说明呋喃甲酸和1,10-邻菲啰啉两种配体的能量可以有效传递给稀土离子,从而增强稀土配合物的发光性.Using rare earth europium,samarium(Eu,Sm)chloride and furoic acid(L)and 1,10-phenanthroline(phen)as raw materials,and 95%ethanol as the solvent,two kinds of new type rare earth complexes([Eu(L)3 phen]2.4H 2O and[Sm(L)3 phen]2.5H 2O)were synthesized.The composition of the complexes were determined with the data form elemental analyzer and thermal analyzer,with infrared spectrum(IR),ultraviolet spectrum(UV)the structure of the ligand and complexes characterized.The analysis results showed that the Eu 3+and Sm 3+in the center of the complexes coordinate with the oxygen atoms in furoic acid(L),at the same time,N atoms in 1,10-phenanthroline(phen)coordinate with Eu 3+and Sm 3+successfully.At room temperature,the fluorescence spectrometer measure result showed that the Eu 3+and Sm 3+in the two complexes all emit characteristic fluorescence,which indicates that the energy of the two ligands-furoic acid and 1,10-phenanthroline can be effectively passed to the rare earth ions,thereby enhancing the luminescence of rare earth complexes.
