Abstract

Using the screen-printing technology, thick films were fabricated by using semiconducting oxide powders such as SnO₂, TiO₂, LaFeO₃, SmFeO₃, and In₂O₃. The microstructure and the gas-sensitive electrical response of the developed thick films were determined. Outdoor field tests were also performed. The use of nano-sized semiconducting oxide powders significantly improved the properties of the gas-sensing materials. Further, acceptable conductance-change performance, along with improved selectivity, was achieved by controlling the microstructure of the oxide through chemical control of the powders and the oxide composition.
