摘　　要：合成了１４种稀土元素与３吡啶甲酸（ＨＬ）及邻菲咯啉（Ｐｈｅｎ）的三元配合物，通过元素分析和化学分析确定其化学组成为ＲＥＬ３·Ｐｈｅｎ，并利用ＩＲ、ＵＶ、１ＨＮＭＲ、ＴＧＤＴＡ和Ｘ射线粉末衍射等手段对配合物进行了表征．研究了Ｅｕ（Ⅲ）及Ｔｂ（Ⅲ）配合物的荧光性质．Fourteen complexes of rare earth with 3pyridine carboxylic acid(HL) and 1,10phenanthroline(Phen) have been synthesized. The complexes have the constitution of REL3Phen(RE=La,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb,Lu,Y) as characterized by elemental analysis, molar conductance measurement, IR, UV, 1H NMR, Xray powder analysis, TG and DTA techniques. The fluorescence intensities of EuL3Phen and TbL3Phen were found to be enhanced by introduction of the neutral ligand Phen.
