[Influence of Pr3+ on Eu3+ luminescence in three component complex system of Eu(ClO4)3-DPSO-phen].
Different nuclear [(Eu(1 - x)Pr(x))(DPSO)(phen)3(ClO4)2]ClO4 x nH2O (x = 0.000-0.200, DPSO as the abbreviation for diphenyl sulfoxide and phen for 1,10-phenanthroline, n = 1-6) coordination compounds were synthesized, and were studied by means of composition analysis, conductance, IR spectra and fluorescence excitation and emission spectra. In the fluorescence spectra it was found that Pr3+ has a great influence on the luminescence of Eu3+. The fluorescence emission intensity of europium perchlorate was enhanced when doped with 0.001-->0.100 mol Pr3+. The local symmetry of Eu3+ site is low in this coordination compounds.
