      Abstract: In search of IR emitting materials a   complex of Yb(III) with an octadentate ligand bearing four   bidentate 8-hydroxyquinolinate subunits connected to a   N,N,N',N"-tetra-aminopropyl-1,2-ethylenediamine anchor [S. Comby,   D. Imbert, A.S. Chauvin, J.C.G. Bunzli, Inorg. Chem. 45 (2006)   732.] has been incorporated into silica glasses obtained by a   special two-step, catalyzed sol-gel method. Photophysical   properties of the resulting thin films are investigated and   compared to those of an aqueous solution 10(-3) M in HBS buffer   (pH 7.4) and of a solid state sample, at room temperature and 10   K. They point to the chelate withstanding the sol-gel process;   moreover the lifetime and quantum yield are comparable and even   slightly better than in aqueous solution.
