Two series of Eu3+-doped homologous-SBA-15 materials (abbreviated as MPTMS-SBA-15: Eu3+ and CTMS-SBA-15: Eu3+) have been synthesized by a hydrolysis-control led technology, in which two novel silane crosslinking reagents (3-(methacryloyloxy) propyltrimethoxysilane (MPTMS) and 3-(chloropropyl) trimethoxysilane (CTMS)) are used as silicate precursor instead of traditional tetraethoxysilane (TEOS). It can be found that the different silicate precursors with different functional groups have influence on the physical properties of the corresponding homologous materials. In comparison to the Pure SBA-15, the BET surface area and pore size of the modified mesoporous materials have been changed. Finally, the characteristic luminescence is observed for the D-5(0) -> F-7(J) (J = 0, 1, 2) transition of Eu3+ ion, suggesting that these kind of homologous-SBA-15 materials are potential host for the luminescence of Eu3+ whose excitation energy can be quenched by Eu3+ to some extent.
