SnOx obtaining by thermal oxidation of nanoscale tin films in the air and its characterization

Investigations on Sn-doped Ni oxide thin films and their use as optical sensor devices

“…(The estimated experimental relative error in ε is ±7%, ρ is ± 6%, and ϕ is ±0.002 eV). It must be mentioned that the bandgap known for SnO 2 is 3.6-4.3 eV, SnO is 2.5-3.0 eV [38], and of NiO is 3.6-4.0 eV [4,5]. Thus, the present measured values agree well with the published data for SnO 2 and NiO.…”

Physical properties of tin oxide thin films improved by vapour chopping

“…Both tetragonal and orthorhombic phases of tin oxide were observed. The orthorhombic phase has been reported by other workers [4,[13][14][15]. The nonchopped tin oxide thin films showed presence of stable tin oxide tetragonal SnO phases with dominant (1 0 1) phase whereas vapour chopped tin oxide thin films showed presence of orthorhombic SnO 2 with dominant (1 1 3) phase.…”

“…Tel. : +91 231 2609245. shevskaya et al [4] have prepared tin oxide by thermal oxidation (in air) of tin films deposited by dc magnetron sputtering in argon plasma on KCl (1 0 0), Si (1 0 0) and fused quartz substrates. In our previous report on tin oxide thin films on glass substrate prepared by chemical reactive evaporation method [5], highly adhesive transparent conducting films with tetragonal structure having refractive indices from 1.76 to 1.92 was obtained.…”

An Aerosol-Based Route to Nanostructured Powders Synthesis in Liquids

“…Indeed, it is reasonable to think that the observed amorphization of the powders is related to the formation of amorphous SnO x (0 < x ≤ 2) during the collection of the produced materials. In that respect, it has been found that Sn metallic nanoparticles undergo a reaction forming a SnO 2 -like phase by air exposure 33 and, similarly, thin Sn films can be completely oxidized to SnO 2 at temperatures as low as 200 C. 36 Elemental analysis was carried out by Energy Dispersive Spectroscopy (EDS) on the as-produced samples in order to evaluate the oxygen content for the particles just taken out from the suspension before centrifugation and washing. From the signals of the oxygen K-edge and the tin L-edge, an atomic ratio for with previous observations of enhanced reactivity, indicating that even brief exposure to air leads to rapid oxidation of the materials.…”
