High ethanol sensitivity in sol–gel derived SnO2 thin films

Electrodynamic properties of aqueous spray-deposited SnO2:F films for infrared plasmonics

“…Many approaches to fabrication of FTO have been reported, including pulsed laser deposition, 27 sol-gel, 28 sputtering, 11,12 sintered powders, 29 and chemical bath deposition. 30 Our approach is an aqueous spray method, which has been shown to give perfectly conformal coatings with plasma frequencies up to the near infrared.…”

Zn-doped and undoped SnO2 nanoparticles: A comparative structural, optical and LPG sensing properties study

“…Several experimental techniques such as co-precipitation [12], sol-gel [13], spray pyrolysis [14], hydrothermal routes [15], etc. have been used for synthesis of nanoparticles.…”

Spray deposited Mg-doped SnO2 thin film LPG sensor: XPS and EDX analysis in relation to deposition temperature and doping

“…Regarding the details, the first step is the dissociative adsorption of LPG to produce H on the interaction surface that reacts with adsorbed atomic oxygen to produce water. As a result, negative charge carriers are re-injected to the bulk and hence the resistance Therefore, by measuring the change in the resistivity of the tin oxide thin films, it is feasible to detect the reducing gases[64].4. Conclusion:Doping of magnesium in SnO 2 , results in the modification of morphological aspects by bringing a favourable crystallite orientation ((110)and(101)) to accommodate oxygen deficiency, thereby yielding enhanced oxygen adsorption.…”
