Abstract

Two bifunctional mesoporous magnetic/luminescent nanocomposites were fabricated. Magnetic (Fe

) cores encapsulated in the mesoporous silica nanospheres and the terbium and erbium complex covalently bonded to the framework of mesoporous silica through the chelate ligand N-(4-benzoic acid-yl)

N'-(propyltriethoxysilyl) (PABA-Si) and 5-[N

N-bis-3-(triethoxysilyl)propyl]ureyl-1

10-phenanthroline (phen-Si)

respectively. The structure

magnetism

and photoluminescence properties of the obtained bifunctional nanocomposites were investigated. The results reveal that the nanospheres possess mesostructures

superparamagnetic behavior

and characteristic luminescence properties of the corresponding lanthanide complexes.
