The inorganic/polymerr hybrid films with good luminescent properties have been obtained by the sol-gel process via incorporating the polymer component doped with rare earth complexes. These films exhibit good toughness and transparency. Their fluorescence spectra and lifetimes indicate that they all have the characteristic luminescence of the central rare earth ions. The lifetimes of these films are longer than those of pure complexes. TEM have showed that the rare earth complexes are dispersed homogeneously in SiO~2/PVB interpenetratiny networks, and the dispersed size is between 20 and 30nm.
