Abstract
A luminescent organic molecule aluminum tris(8-hydroxyquinoline) (Alq 3) has been successfully introduced in the pores of amino-functionalized mesoporous SBA-15 (APS-SBA-15). An obvious blue-shifted photoluminescence (PL) of Alq 3 was observed. In the pores of APS-SBA-15, the Alq 3 organic molecules exhibited efficient and intense PL as monomers and the emission intensities increased with increasing Alq 3 concentration.
