摘要: Three different types of organic–inorganic hybrid materials formed by trivalent lanthanide (Ln3+ = Eu3+, Tb3+) complexes covalently grafted to silica-, titania-, or silica/titania-based hosts have been prepared and fully characterized. Since the organic ligand 2-sulfanylpyridine-3-carboxylic acid (SPC), a derivative nicotinic acid, exhibits three potential binding sites (pyridine N, sulfhydryl S carboxylic O), multifunctional precursor can be through reaction group with titanium alkoxide modification silane crosslinking reagents. Thus, Eu3+ Tb3+ are synthesized coordination Ln3+ ions heterocyclic in during sol–gel process. The obtained were characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), differential calorimetry (DSC), thermogravimetric analysis (TG), Fourier transform infrared (FTIR) spectroscopy, photoluminescence (PL). detailed PL studies showed that, compared titania-based (denoted as Ln–SPC–Ti), silica- Ln–SPCSi Ln–SPCSi–Ti, respectively) exhibited higher luminescence intensity emission quantum efficiency.
