摘要
Tin dioxide thin films have been prepared by both spray pyrolysis and thermal evaporation on alumina substrates. The main purpose was to determine suitable microstructural and electrical properties for ethanol sensors. Chlorine content in precursor solutions used in the spray pyrolysis technique affects both the structural and the electrical properties of the films. Chlorine-free precursors were prepared to achieve porous SnO2 films. Ethanol sensing properties were determined and compared to thermally evaporated films.
