Abstract
SnO2 thick film gas sensor has been prepared by applying low frequency (0.1 Hz) AC electric fields to a stable suspension of SnO2 nanoparticles in acetylacetone. Parallel gold electrodes were used as the deposition substrate. Effect of CO, O2 and H2 gas exposure as well as ethanol vapor on conductivity of the SnO2 film at 300 °C is investigated. Results show that the sensor is sensitive and its response is repeatable. This work shows that ACEPD can be used as an easy and cheap technique for fabrication of electronic devices such as ceramic-based gas sensors.
