Electrostatic sprayed SnO2 and Cu-doped SnO2 films for H2S detection
Sensors and Actuators B: Chemical, 2008This paper presents the ability of electrostatic sprayed tin oxide (SnO2) and tin oxide doped with copper oxide (1, 2, and 4 at.% Cu) films to detect different pollutant gases, i.e., H2S, SO2, and NO2. The influence of a copper oxide dopant on the SnO2 morphology is studied using scanning electron microscopy (SEM) technique, which reveals a small ...

Sensing Behavior of SnO2-Graphene Nanocomposites
2013The sensing properties of SnO2-graphene composites prepared by a one-pot non-aqueous procedure assisted by microwave treatment have been investigated. The combined characteristics of the microwave heating and the “benzyl alcohol route” allowed to selectively grow, at the temperature of 185 °C and in only few minutes, metal oxide nanoparticles on the ...

Precipitation of SnO2 nano-crystallites from Na2O/B2O3/SnO2/(Al2O3) glasses
Journal of Non-Crystalline Solids, 2005Abstract The system Na2O/B2O3/SnO2/(Al2O3) exhibits a fairly large glass forming range, samples with up to 10 mol% SnO2 could be prepared. The glasses were thermally treated at temperatures in the range from 580 to 820 °C. From glasses with large [Na2O]/[B2O3]-ratios, Na2SnO3 crystallized, while [Na2O]/[B2O3]-ratios ⩽ 1.125 resulted in the ...

Redistribution of SnO2 particles in Ag/SnO2 materials during rapid solidification
Materials Science and Engineering: A, 2007Melt spinning experiments were performed on Ag-12 wt.% SnO2 contact materials with and without CuO addition for the purpose of simulating the rapid solidification process of an instantaneously remelted thin surface layer during arcing. The microstructure of the rapidly solidified ribbons was investigated using optical and scanning electron microscopy ...

Thin films of undoped, 20 wt. % flourine-doped and 2 wt. % antimony-doped tin oxide on glass substrates at 410 (+/- 5) degrees C were deposited by spray pyrolysis technique. The effect of 20 wt. % fluorine(F) and 2 wt. % antimony(Sb) doping on the structural, electrical and optical properties of tin oxide thin films were investigated. X-ray diffraction
