SnO2 and SnO2:Pt thin films used as gas sensors

Sensors and Actuators B: Chemical, 1997
Abstract 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, 2007
Gas-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 ...

Microstructure and properties of Ag–SnO2 materials with high SnO2 content

Journal of Alloys and Compounds, 2014
Abstract The microstructure and properties of Ag–SnO2 materials with high SnO2 content were investigated. The microstructure, physical properties and arc erosion behavior of Ag–SnO2 materials with high SnO2 content were studied. The results showed that the Ag–SnO2 materials with high SnO2 content show homogeneous microstructure with high hardness and

Preparation of SnO2 nanorods by annealing SnO2 powder in NaCl flux

Journal of Materials Chemistry, 2002
SnO2 nanorods having the rutile structure have been prepared by annealing fine SnO2 powder in a NaCl flux. The starting SnO2 powder, the NaCl flux, and surfactant NP9 were mixed and heated at 800 °C for 2.5 h. The nanorods have diameters of ca. 20–40 nm and lengths of up to 1 μm.

Tailoring of highly porous SnO2 and SnO2-Pd thin films

Materials Chemistry and Physics, 2019
Abstract Tin oxide is a material that attracts attention due to variety of technological applications. The main parameters that influence its properties are morphology, crystalline structure and stoichiometry. Researchers try to develop nanostructured thin films with tunable parameters that would conform its technological applications.

Silver layer instability in a SnO2/Ag/SnO2 trilayer on silicon

Thin Solid Films, 2012
Abstract Trilayers of SnO2/Ag/SnO2 deposited on oxidized Si (100) substrates at room temperature become unstable after annealing at 100 °C and 200 °C, exhibiting five phenomena – formation of internal Ag hillocks, cracking of the top SnO2 layer above internal Ag hillocks, penetration of Ag/Ag grain boundaries by SnO2 leading to grain pinch-off ...
