摘要
用沉淀法在无水乙醇溶液中,合成了铽、3,5-二氯水杨酸(DclSal)、N-苯基-乙萘胺(NphNAm)三元配合物。用元素分析、红外光谱、X射线粉末衍射及荧光光谱等进行了表征。结果表明:三元配合物的化学组成为Tb(DClSal)3(NPhNAm)2,其发射峰位于544 nm,归属于稀土Tb3+离子的5D4→7F5的跃迁。
A solid complex of Terbium -DClSal (3,5-Dichlorosalicylic acid) NPhNAm(N-Phenyl-β-Naphthylamine) was synthesized by co-precipitation in absolute ethanol solution at 60 ℃. The complex was characterized by elemental analysis, IR absorption spectra, X-ray powder diffraction, and fluorescence spectrum. The result showed that it is crystal and its chemical composition is Tb(DClSal)3 (NPhNAm)2. Its emission peak locates at 543 nm, which is attributed to 5D4→TFs of Tb^3+ ion.
