Improvement of sensitivity characters of Tin dioxide thin films uses as detector for toxic and explosive gases sensors

Abstract

The Tin dioxide films obtained by spray hydrolysis deposition method were improvement to be used as development elements for gases sensors. We were studied sensitivity and selectivity of these films mixture CH4 and CO gases and alone, we found that the degree of sensitivity of films when there is gases higher as compared without gases. Due to their high sensitivity and particular selectivity SnO2 films becomes perspective material for sensitive elements of gases sensors towards toxic and explosive gases like methane and carbon oxide for example to these kinds of gases.
