SnO2:Eu nanocrystallites in SnO2 monolithic xerogels

Chemical Physics Letters, 1992
Abstract By simple room temperature broad band time-resolved spectroscopy it was possible to discriminate different Eu3+ spectra in SnO2 monolithic gels obtained by a sol—gel synthetic route. Nanocrystalline domains of the cassiterite-like SnO2:Eu could be easily identified in the transparent medium.

Oxygen Vacancies Enabled Porous SnO2 Thin Films for Highly Sensitive Detection of Triethylamine at Room Temperature.

ACS Applied Materials and Interfaces, 2020
Detection of volatile organic compounds (VOCs) at room temperature (RT) currently remains a challenge for metal oxide semiconductor (MOS) gas sensors. Herein, we for the first time report on the utilization of porous SnO2 thin films for RT detection of ...

Preparation of Fe-SnO2@CeO2 nanocomposite electrode for asymmetric supercapacitor device performance analysis

, 2021
In this work, we report enhanced specific capactance and cycle stability of Fe-SnO2@CeO2 electrode for supercapacitor applications. The Fe-SnO2@CeO2 nanocomposite was synthesized through a simple chemical co-precipitation method.

Microstructure and structure of NiO–SnO2 and Fe2O3–SnO2 systems

Applied Surface Science, 2003
Abstract 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.

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.
