Influence of cerium (IV) ions on the inorganic and organic phase for preparation of a siloxane-PMMA based film on tin plate substrate
(2008-12-01)
Tinplate is one of the most widely used food canning materials, however, there are significant problems related to the use of tinplate cans, such as alterations in sensory features affecting food quality and corrosion ...
Optical and transport properties of rare-earth trivalent ions located at different sites in sol-gel SnO2
(2010-12-01)
Photoluminescence and photo-excited conductivity data as well as structural analysis are presented for sol-gel SnO2 thin films doped with rare earth ions Eu3+ and Er3+, deposited by sol-gel-dip-coating technique. ...
Sol-Gel Erbium-Doped Silica-Hafnia Planar and Channel Waveguides
(2003-11-27)
Erbium activated SiO2 -HfO2 planar waveguides, doped with Er3+ concentrations ranging from 0.01 to 4 mol%, were prepared by sol-gel method. The films were deposited on v-SiO2 and silica-on-silicon substrates using dip-coating ...
Nucleation and crystallization of titania nanoparticles in silica titania planar waveguides: A study by low frequency Raman scattering
(2004-07-28)
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 ...
Hydroxyapatite Coating Deposited On Grade 4 Titanium By Plasma Electrolytic Oxidation

Investigation of photoinduced electrical properties in the heterojunction TiO2/SnO2
(Trans Tech Publications Ltd, 2014-01-01)
TiO2/SnO2 thin films heterostructures were grown by the sol-gel dip-coating technique. It was found that the crystalline structure of TiO2 depends on the annealing temperature and the substrate type. TiO2 films deposited ...
Optical excitation of charge carriers from intra-bandgap states in Ce-doped SnO2 thin films
(2008-05-21)
Optical excitation of Ce3+-doped SnO2 thin films, obtained by the sol-gel-dip-coating technique, is carried out and the effects on electrical transport are evaluated. Samples are doped with O. lat% of Ce, just above the ...
