Abstract Four series of solid complexes including RExTb1-x(acac)3phen and RExTb1-x(acac)3bipy (RE=La, Y;x=0, 0.10, 0.20, 0.30, 0.50, 0.70, 0.90, 1.00) were synthesized. These complexes were characterized by IR spectra and XRD. Photoluminescence (PL) properties of these complexes were studied. The relation between their fluorescence intensities and the content of doped ions was also discussed. The experimental results show that the PL intensity of Tb3+ was sensitized by La3+ or Y3+, and La3+ is better than Y3+ in enhancing the fluorescence of Tb3+. When x=0.1-0.3, the fluorescence intensities of most doped complexes are stronger than their corresponding pure Tb3+ complex.
