Two novel core-shell composites SiO₂@PMDA-Si-Tb, SiO₂@PMDA-Si-Tb-phen with SiO₂ as the core and terbium organic complex as the shell, were successfully synthesized. The terbium ion was coordinated with organic ligand forming terbium organic complex in the shell layer. The bi-functional organosilane ((HOOC)₂C₆H₂(CONH(CH₂)₃Si(OCH₂CH₃)₃)₂ (abbreviated as PMDA-Si) was used as the first ligand and phen as the second ligand. Furthermore, the silica-modified SiO₂@PMDA-Si-Tb@SiO₂ and SiO₂@PMDA-Si-Tb-phe ...[more]
