The bi-rare earth complexes EuTb(m-MBA)6(phen)2*2H2O, TbY(m-MBA)6(phen)2*2H2O were synthesized by the reaction of RECl3 with m-methylbenzoic acid and 1,10-phenanthroline in ethanol solution, where m-MBA=m-methylbenzoate and phen=1,10-phenanthroline. The luminescence properties of the title complexes were studied in comparison with the corresponding complexes Eu2(m-MBA)6(phen)2*2H2O and Tb2(m-MBA)6(phen)2*2H2O respectively. The results indicate that the emission intensity from europium ion can be greatly enhanced by the terbium ion, while the emission from terbium ion was strongly quenched by europium ion in EuTb(m-MBA)6(phen)2*2H2O; the emission intensity from terbium ion can be greatly enhanced by yttrium ion in TbY(m-MBA)6(phen)2*2H2O. The mechanism about the results was discussed.
