A study of gas sensing properties of ZnO nanostructures activated by UV light

Marcin Procek, Tadeusz Pustelny


In this paper the response of resistance gas sensors is investigated, based on zinc oxide nanostructures to NO2. The research is focused on the influence of ultraviolet light on the operation of such sensors at room temperature. Comparative experiment results are presented and discussed for thermal (200 oC) and UV (LED: λ=390 nm) activation in different carrier gases (air and nitrogen).
