Novel hybrid materials containing covalently bonded Terbium-benzoic acid complex in mesoporous silicaSBA-15 (denoted as Tb-SBA-15 ) were prepared via co-condensation of tetrethoxysilane (TEOS) and N-(4-benzoicacid-yl), N'-(propyltriethoxysilyl) urea (denoted as PABI).XRD, FTIR and luminescence spectroscopy were employed to characterize Tb-SBA-15.When monitored by the ligand absorption wavelength (270 nm), Tb-SBA-15 displays the emission of Tb3+ (5D4→7Fj (j = 6, 5, 4, 3 ) transition) due to the energy transfer from the ligands to Tb3+.
