GHGs detection by tuning the operating temperature of Sn1-xGdxO(4-x)/2

Chemical sensors translate charge exchange chemical interactions into electrical resistance variations. The interactions are modulated by the operating temperature and facilitated by doping the base material, which is generally a metal oxide semiconductor. In the present study, we doped SnO 2 with Gd to increase the vacancies number and make it more reactive. The detection potential of greenhouse gases is investigated by modulating the operating temperature detection of sensors based on $\mathrm{S_{1-x} G d_{x} O_{(4-x) / 2}}$ thick layers.
