    Nanocomposites of titania and hybrid matrix with high refractive index

    A sol–gel route for TiO2 nanocrystals (NCs) synthesis has been developed at low temperature without surfactants. Synthetic and processing parameters have been optimized to maximize particles’ colloidal stability ...

    Silver-sensitized erbium-doped ion-exchanged sol–gel waveguides

    Ag- and Er-doped glass films have been synthesized with a combined sol–gel and ion-exchange route. The introduction of silver as erbium sensitizer in the film was obtained by ion exchanging Er-doped SiO2–Al2O3–Na

    Optical CO gas sensing using nanostructured NiO and NiO/SiO2 nanocomposites fabricated by PLD and sol–gel methods

    Several kinds of NiO-based nanostructured films were prepared by pulsed-laser deposition (PLD) and sol–gel method, and CO sensing properties (1%, balanced by N2) of these films were studied. The sensitivity, defi...

    Optical extinction resonance of Au and Ag clusters formed by ion irradiation in SiO2 and Al2O3

    Three methods based on ion-beam irradiation were used to fabricate Ag and Au colloids in silica and alumina. Their surface-plasmon resonance in the visible was characterised by transmittance measurements and i...
