Lanthanide complexes-functionalized ordered mesoporous TiO2: Multicolor emission (visible and near-infrared luminescence) based on visible-light sensitization

The ordered mesoporous hybrid titania materials LnDB-OMT (Ln = Eu, Sm, Yb, Nd) were successfully synthesized by anchoring lanthanide complexes to the ordered mesoporous hybrid titania via covalent linking. Under excitation with visible light, the hybrid matrices showed characteristic visible (Eu3+, Sm3+) as well as near-infrared (Sm3+, Yb3+, Nd3+) luminescence.261
