Nanostructured TiO2-based composites for light absorption
(Trans Tech Publications Ltd, 2014-01-01)
Metal oxidenanocomposites were prepared by two different routes: polyol and sol-gel. Characterization by X ray diffraction showed that the first processproducesdirectly a two-phase material, while the sol-gelpowder never ...
Nucleation and crystallization of titania nanoparticles in silica titania planar waveguides: A study by low frequency Raman scattering
SiO2 (1-x) - TiO2 (x) waveguides, with the mole fraction x in the range 0.07 - 0.20 and thickness of about 0.4 μm, were deposited on silica substrates by a dip-coating technique. The thermal treatments at 700-900°C, used ...
