Lanthanide luminescence has gained wide attention because trivalent lanthanide ions generally display intense luminescence in the visible and near-IR regions.Recently, our group has reported some new materials with excellent lanthanide luminescent properties.A series of bifunctional architecture combining the useful functions of superparamagnetism (Fe3O4) and luminescence of lanthanide complex into one system have great potential in biological applications, such as cell imaging and drug delivery.[1,2] Encapsulation of lanthanide complex into titania sol instead of silicaextend the range of organic-inorganic hybrid materials.[3] Luminescent hybrid materials, based on physically doping (or covalently bonding) europium complexes into PMMA-co-Sn12 Cluster, have been prepared.Such materials could be redissolved in organic solvent and repeatedly gelled, which endows them with shape controllability.[4] Furthermore, single or bimetallic lanthanide metal-organic frameworks (Ln-MOFs) nanocrystals have been obtained through an easily scalable method using carboxylate salts as capping reagent for specific applications in thin film devices.
