Photoactive metallic (Al3+, Zn2+, Eu3+, Tb3+, Er3+, Nd3+) mesoporous hybrid materials by functionalized 8-hydroxyquinolinate linkage covalently bonded SBA-15

A kind of monomer HQSi has been achieved and its functionalised SBA-15 hybrid materials have been synthesized. Luminescent hybrid mesoporous materials consisting of different metal ions (Al3+, Zn2+, Eu3+, Tb, Er3+, Nd3+) complex covalently bonded to the mesoporous materials network have been obtained via this sol–gel approach. The resulting materials were characterized by powder X-ray diffraction, N2 adsorption/desorption, and thermogravimetric analysis. Luminescence spectra of these lanthanide-complex functionalized materials were also recorded. While irradiated with a UV lamp, the finally materials show blue-green color fluorescence. The good luminescent performances enable these luminescent hybrid mesoporous materials to have potential applications in the field of photoluminescence.
