| Abstract: | Some polynuclear complexes of benzoic acid with lanthanum, dysprosium and praseodymium were synthesized by the reaction of trivalent rare earth chlorides with sodium benzoate in aqueous solution. Their composition is expressed with the general formula RE(BA) 3 where BA=C 6H 5COO -, RE=La 3 , Dy 3 ,Pr 3 , the general formula of double nucleus complexes is La xDy 1-x (BA) 3, x=0.75,0.50,0.25; the general formula of triple nucleus complexes is La 0.25 Dy xPr 0.75-x (BA) 3 ,x=0.65,0.55,0.45. These new prepared complexes have been characterized by means of IR spectra, UV spectra, fluorescence emission spectra. The relation of their luminous intensities upon their quantity of Dy 3 , Pr 3 , and La 3 ion has been studied. |
