The Molar conductivity indicates that all the complexes are nonelectrolyte. IR spectra show the ligand is bonded with RE ion through its oxygen atom in hydroxyl group of phenol; NO3 is coordinated as a symmetrical chelating bidentate group; the coordinated atoms of DMF and DMSO are the oxygen atoms in carbonyl and sulfoxyl groups. Fluorescence spectrum suggests that the Tb3+complexes have characteristic luminescence and its fluorescence intensity is enhanced after doping with La3+, Gd3+, Y3+, influence of doping ions and neutral ligands have also been discussed.
