Abstract

Europium (III) and Terbium (III) complexes of types [Eu(L)Cl(H2O)3] and [Tb(L)OAc(H2O)3] (H2L = Schiff base derived from condensation of 3-(phenyl/substituted phenyl)-4-amino-5-mercapto-1,2,4-triazole with benzil/diacetyl) have been synthesized by the reactions of anhydrous europium (III) chloride and anhydrous terbium (III) acetate with Schiff bases in ethanol. The synthesized complexes were characterized on the basis of elemental analysis, spectroscopic measurement, magnetic moment, electrical conductance and X-ray diffraction studies. The photoluminescence properties of europium (III) and terbium (III) complexes have also been studied. Europium (III) and Terbium (III) complexes show very strong characteristic emission in red and green regions, respectively.
