E-beam deposited SnO2, Pt–SnO2 and Pd–SnO2 thin films for LPG detection

Thin Solid Films, 1999
Abstract The electron-beam evaporation method was used to deposit undoped and Pt (or Pd) doped SnO 2 thin films. After careful study of their physical properties, SnO 2 thin films with suitable growth conditions were selected for probing their response to LPG and other common household gases.

Electron spectroscopic studies on films of SnO2 and SnO2:Sb

Surface and Coatings Technology, 1987
Abstract Pure and antimony-doped SnO2 films have been deposited by two different techniques: metal-organic chemical vapour deposition (MO-CVD) and spray pyrolysis of SnCl4 in the presence of air with different concentrations of antimony. X-ray and UV photoelectron spectroscopic studies have been carried out on these films and the combined data from ...

SnO2@MCC and SnO2@C Composites: Synthesis and Properties

Russian Journal of Inorganic Chemistry, 2019
A method is advanced to prepare SnO2@MCC composites in the course of hydrolysis of flax cellulose fiber by SnCl2-containing 10% aqueous nitric acid. The thus-prepared SnO2@MCC composites have a tin dioxide average crystallite size of 3.8 nm. SnO2@MCC pyrolysis under an inert atmosphere yield carbon composites SnO2@C and SnO2/Sn@C.

SnO2 by XPS

Surface Science Spectra, 1993
Tin and various tin compounds have wide utility in coatings, electronics, and catalysts, as well as having numerous biological applications. Distinguishing between different tin compounds on surfaces is an important aspect of research in many of these disciplines. In this work, x-ray photoelectron spectroscopy has been used to obtain comparison spectra

Electroless deposition of Sno2 and antimony doped SnO2 films

Journal of Physics and Chemistry of Solids, 1985
Abstract Thin polycrystalline films of SnO 2 and antimony doped SnO 2 have been prepared by simple economic electroless deposition technique. The transmittance in the visible range and the reflectance in the i.r. range for SnO 2 films are ∼80% and ∼70%, respectively, with resistivity ∼10 −2 Ω cm.

Preparation of porous SnO2 helical nanotubes and SnO2 sheets

Materials Chemistry and Physics, 2013
abstract We report a surfactant-free chemical solution route for synthesizing one-dimensional porous SnO 2 helical nanotubes templated by helical carbon nanotubes and two-dimensional SnO 2 sheets templatedby graphite sheets. Transmission electron microscopy, X-ray diffraction, cyclic voltammetry, and galva-nostatic dischargeecharge analysis are used to

Excimer Laser Preparation of SnO2 and SnO2/TiO2 Nanoparticles

2011
A single pulse of an ArF excimer laser induces efficient oxidation of Sn(CH3)4 and Sn(CH3)4/Ti(Oi-C3H7)4 in the gas phase. The direct deposition of stoichiometric tin dioxide, tin monoxide and mixed tin/titanium dioxide is demonstrated. Structural changes at 300°C and 500°C in both vacuum and air are studied by means of XRD and Raman spectroscopy ...

Room temperature highly toxic NO2 gas sensors based on rootstock/scion nanowires of SnO2/ZnO, ZnO/SnO2, SnO2/SnO2 and, ZnO/ZnO

Sensors and Actuators B: Chemical, 2021
Abstract Grafted structures between SnO2 and ZnO nanowires were realized in a two-step process of growth. First, the rootstocks of SnO2 or ZnO nanowires were synthesized by thermal evaporation technique. Second, a thin Au layer was sputter deposited on the sample and synthesis of nanowire scions of ZnO or SnO2, respectively, on the rootstocks was ...

Growth of IrO2, SnO2, and SnO2:IrO2 crystals

Materials Research Bulletin, 1976
Abstract Crystals of IrO 2 , SnO 2 , and SnO 2 :IrO 2 have been grown by chemical vapor transport. The IrO 2 crystals are larger than any previously reported. The SnO 2 and SnO 2 :IrO 2 crystals are optically clear and are suitable for optical properties studies. This is the first report on the growth of SnO 2 :IrO 2 crystals.
