Preparation, characterization and luminescence properties of core-shell ternary terbium composites SiO₂₍₆₀₀₎@Tb(MABA-Si)•L.

ABSTRACT: Two novel core-shell structure ternary terbium composites SiO₂₍₆₀₀₎@Tb(MABA-Si)·L(L:dipy/phen) nanometre 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 was found that the first ligand MABA-Si of terbium ternary complex hydrolysed to g
