Abstract

This report discusses SnO(2), having n-type semiconducting properties, which have been deposited onto alumina sheets in order to be tested as ozone sensors. They were characterized for morphology, structure and chemical composition by X-ray photoelectron spectroscopy (XPS), atomic emission spectroscopy (AES), glance angle X-ray diffractometry (GAXRD) and ellipsometry. The responses were analyzed at temperatures ranging 100 C to 300 C at the JRC's European Reference Laboratory for Air Pollution (ERLAP). The results look satisfactory in terms of both sensitivity and interferences due to NO(2) and moisture. The rate of response looks encouraging for being utilized for the ozone environmental control. The long term stability, however, needs further investigations.
