文摘

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 Eu³⁺ and Tb³⁺ ions. Furthermore, the decay times and emission quantum efficiency of Eu³⁺ hybrid material are also determined.
