Electroless deposition of Sno2 and antimony doped SnO2 films
Journal of Physics and Chemistry of Solids, 1985Abstract 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.

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

Growth of IrO2, SnO2, and SnO2:IrO2 crystals
Materials Research Bulletin, 1976Abstract 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.

Excimer Laser Preparation of SnO2 and SnO2/TiO2 Nanoparticles
2011A 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 ...

SnO2 and SnO2:Pt thin films used as gas sensors
Sensors and Actuators B: Chemical, 1997Abstract SnO2 and SnO2:Pt thin films, prepared by chemical spray deposition, have been used as gas sensors. The electrical characterization results and their sensing properties in the presence of CO are reported. The films were grown by chemical spray deposition on glass substrates at different temperatures.

Comparison of Gas Sensitivity between SnO2 nanoparticles and SnO2 nanobelts
2007 International Conference on Information Acquisition, 2007Gas-sensing components have been manufactured with prepared SnO2 nanoparticles and SnO2 nanobelts. Their performance indicates that the SnO2 nanoparticles and the SnO2 nanobelts have similar relations between sensitivity and working temperature, but SnO2 nanobelts have lower max sensitive temperature to LPG than SnO2 nanoparticles, and SnO2 nanobelts ...

Electron spectroscopic studies on films of SnO2 and SnO2:Sb
Surface and Coatings Technology, 1987Abstract 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 ...

Microstructure and structure of NiO–SnO2 and Fe2O3–SnO2 systems
Applied Surface Science, 2003Abstract The microstructure and the structure of NiO–SnO 2 and Fe 2 O 3 –SnO 2 were studied by X-ray diffraction (XRD) and adsorption analysis (BET). The segregation of Ni or Fe on the surface of SnO 2 was observed even in specimens with 30 mol% addition.

Nano-grain SnO2 electrodes for high conversion efficiency SnO2–DSSC
Solar Energy Materials and Solar Cells, 2011Abstract The nano-grain ZnO/SnO 2 composite electrode was prepared by adding 5 w% of the 200–250 nm ZnO particles to the 5 nm SnO 2 colloid in the presence of hydroxypropylcellulose (M.W.=80,000). The nano-grain SnO 2 electrode was obtained by removing the ZnO particles from the composite electrode using acetic acid.
