Paper Abstract

The paper presents gas sensors based on ZnO nanostructures, which were obtained from zinc acetate in a very simple and repeatable process. Obtained structures were characterised using Raman spectroscopy and scanning electron microscopy. The ZnO nanostructures were applied as receptor layers in chemoresistive gas sensors onto interdigital transducers, using drop-coating. Sensor responses to low concentrations (1 ppm) of NO2 in the air, at different operating temperatures (room temperature 23°C (R.T.), 100°C and 200°C) and under different lighting conditions (dark conditions and UV irradiation – LED λ = 390 nm) are compared and discussed. Obtained results show that proper combination of elevated temperature and illumination by UV can improve sensor properties and allow it to operate at a lower temperature.
