Microstructural Studies

The present work shows the SO2 gas sensing property of SnO2 thin film based sensor prepared by using RF sputtering technique. Different catalysts (MgO and V2O5) in form of nanoclusters having diameter of 600 μm have been loaded on SnO2 surface to detect SO2 gas. The sensing response of all these films towards SO2 is monitored. Microstructural studies have been carried out using XRD and UV-Visible Spectrophotometer and a good correlation has been found between the microstructural and gas sensing properties of these deposited samples. Both catalysts when incorporated with SnO2 film show high selectivity towards SO2 gas at lower operating temperature. MgO gives a sensitivity of 317% at an operating temperature of 280°C towards 500 ppm of SO2 gas whereas V2O5 catalyst gives a sensitivity of 166% at 280°C for the same amount of gas.

Film Form

CuInO2phase, a p-type semi-conducting oxide was successfully stabilized in thin film form by pulsed laser deposition technique and the deposition parameters were optimized. The gas sensing studies carried out on thin film of CuInO2for different concentrations of NOxexhibited a decrease in resistance, a characteristic of p-type semiconductor. The thin film responded to 4 vppm of NOxin air. The CuInO2thin film did not respond to trace levels of hydrogen, ammonia and petroleum gas at this operating temperature and thus offering selectivity to NOx.

Hydrogen Peroxide Vapor

Abstract. Thin-film hydrogen peroxide vapor sensors made from Co-doped SnO2 and La-doped ZnO were manufactured using the high-frequency magnetron sputtering method. Thicknesses of deposited doped metal oxide films were measured and their morphology was investigated. The gas sensing characteristics of the prepared sensors were measured at different concentrations of hydrogen peroxide vapors and different operating temperatures of the sensor. It was found that both sensors made from doped metal oxides SnO2 and ZnO exhibit a sufficient response to 10 ppm of hydrogen peroxide vapors at the 200 and 220 ∘C operating temperature, respectively. It was established that the dependencies of the response on hydrogen peroxide vapor concentration have a linear character for prepared structures at the 150 ∘C operating temperature and can be used for determination of hydrogen peroxide vapor concentration.
