UV-Light-Induced Fluctuation Enhanced Sensing by WO3-Based Gas Sensors

WO 3 -based gas sensors were investigated under UV-light irradiation and at different working temperatures with the object of achieving superior sensitivity and selectivity. Resistance fluctuations in the WO 3 layer were studied together with dc resistance measurements. The data were taken in synthe...

Zusammenfassung:WO 3 -based gas sensors were investigated under UV-light irradiation and at different working temperatures with the object of achieving superior sensitivity and selectivity. Resistance fluctuations in the WO 3 layer were studied together with dc resistance measurements. The data were taken in synthetic air, ethanol, nitrogen dioxide, and mixtures of these gases. We conclude that UV irradiation can easily be applied to enhance the gas sensing properties of a WO 3 layer.
