Abstract
A sensor sensitive to acetone vapors based on a Fe2O3❬Sn❭ metal oxide solid solution was fabricated by high-frequency magnetron sputtering. The gas-sensitivity of the manufactured sensor are investigated. The Fe2O3❬Sn❭ sensor shows sensitivity to acetone vapors starting from a temperature of 150°C under the influence of ultraviolet rays. The increase in operating temperature was accompanied by a linear increase in the sensor response. Exposure to ultraviolet rays not only improved the sensitivity of the sensor under study, but also increased its performance. A sensor based on Fe2O3❬Sn❭ can be successfully applied in acetone detectors.
