摘　　要：合成了钐(Ⅲ)的丙烯酸(AN)的二元小分子配合物Sm(AN)2.2 H2O和三元小分子配合物Sm(AN)3.Phen(Phen为邻菲啰啉),通过溶解性能、红外光谱对配合物进行了表征.配合物的紫外光谱和荧光光谱表明,配合物发射Sm(Ⅲ)的特征荧光,丙烯腈的三重态能级与Sm3+最低能态具有良好匹配;第二配体Phen具有荧光增强作用.The binary and ternary Sm（Ⅲ） complexes with the acrylonitrile and 1,10-phenanthroline（Phen） have been prepared.The composition of the complexes was determined to be Sm（AN）3·2H2O and Sm（AN）3·Phen by solubility performance and FT-IR spectra.The UV and fluorescence spectra of the complexes showed characteristic fluorescence of Sm（Ⅲ）.The energy level of the triplet state of AN ligand match well with the lowest excited state level of Sm3＋ ion.The second ligand Phen showed en-hancement effect on the fluorescence of the complexes.
