Two novel core-shell structure ternary terbium composites SiO2(600)@Tb(MABA-Si)•L(L:dipy/phen) nanometer luminescence materials were prepared by ternary terbium complexes Tb(MABA-Si)•L2•(ClO4)3•2H2O shell grafted onto the surface of SiO2 microspheres. And corresponding ternary terbium complexes were synthesized using (CONH(CH2)3Si(OCH2CH3)3)2 (denoted as MABA-Si) as first ligand and L as second ligand coordinated with terbium perchlorate. The as-synthesized products were characterized by means of IR spectra, 1HNMR, element analysis, molar conductivity, SEM and TEM. It found that the first ligand MABA-Si of terbium ternary complex hydrolysed to generate the Si-OH and the Si-OH condensate with the Si-OH on the surface of SiO2 microspheres, then ligand MABA-Si grafted onto the surface of SiO2 microspheres. The diameter of SiO2 core of SiO2(600)@Tb(MABA-Si)•L was about 600 nm.. Interestingly, the luminescence properties demonstrate that the two core-shell structure ternary terbium composites SiO2(600)Tb(MABA-Si)•L(dipy/phen) exhibit strong emission intensity, which are 2.49 and 3.35 times higher than that of the corresponding complexes Tb(MABA-Si)•L2•(ClO4)3•2H2O, respectively. Luminescence decay curves show that core-shell structure ternary terbium composites have longer lifetime. Excellent luminescence properties enable the core-shell materials to have potential applications in medicine, industry, luminescent fibres and various biomaterials filed.
