A new sort of chemically bonded lanthanide organic-inorganic hybrid material has been constructed through the bifunctional sulfoxide molecular bridge (MSAPSi, which is functionalized 2-(methylsulfinyl) acetophenone (MSAP) by 3-(triethoxysilyl)-propyl isocyanate (TESPIC)) linking Si-O-Ti-O inorganic networks The results suggest that the obtained hybrid materials are totally amorphous without phase separation phenomenon and exhibit the characteristic luminescence of Eu(3+) and Tb(3+) ions Furthermore, the decay times and emission quantum efficiency of Eu(3+) hybrid material are also determined.
