TI  - Novel sol-gel precursors for thin mesoporous eu(3+)-doped silica coatings as 
      efficient luminescent materials.

AB  - Europium(III) ions containing mesoporous silica coatings have been prepared via a 
      solvent evaporation-induced self-assembly (EISA) approach of different 
      single-source precursors (SSPs) in the presence of Pluronic P123 as a 
      structure-directing agent, using the spin-coating process. A deliberate tailoring 
      of the chemical composition of the porous coatings with various Si:Eu ratios was 
      achieved by processing mixtures of tetraethylorthosilicate (TEOS) and 
      Eu(3+)-coordinated SSPs. Small-angle X-ray scattering (SAXS) and transmission 
      electron microscopy (TEM) analyses demonstrate that the thin metal oxide-doped 
      silica coatings consist of a porous network with a short-range order of the pore 
      structure, even at high europium(III) loadings. Furthermore, luminescence 
      properties were investigated at different temperatures and different degrees of 
      Eu(3+) contents. The photoluminescence spectra clearly show characteristic 
      emission peaks corresponding to the (5)D0 --> (7)FJ (J = 0-5) transitions resulting 
      in a red luminescence visible by the eyes, although the films have a very low 
      thickness (150-200 nm).
