| Abstract: | Three series of solid complexes of Eu_xRE_ 1-x(dbm)_3phen(RE=La,Y,Gd,x=0.00,0.10,0.30,0.50,0.70,0.80,0.90,1.00) were synthesized and then characterized by elemental analysis,molar conductance,IR spectra and XRD.Photoluminescence(PL) properties of these complexes were studied.The relations between their fluorescent intensities and the content of doped ions were also discussed.La 3 ,Y 3 and Gd 3 all could sensitize the fluorescence of Eu 3 in the order of La 3 >Y 3 >Gd 3 . |
