| Abstract: | 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. |
