Luminescent lanthanide-based nanocomposites (LnNCs) with intense and stable luminescence in aqueous media are in high demand for sensing and biological applications. Herein we report a new water-soluble LnNCs that prepared through a very simple and green procedure, with bright green luminescence dominated by 5D4→7F5 transition (542nm) of Tb3+, showing improved luminescence behavior compared with the...
In situ synthesis of terbium carboxyl complexes in an organic-inorganic hybrid matrix by a sol-gel process has been proposed. The formation of terbium carboxyl complexes in the hybrid matrix is confirmed by the luminescence spectra and IR spectra. It is observed that the location at the amino group in aminobenzoic acid has a large effect on the luminescence properties and lifetimes. Furthermore, the...
