Paper Abstract

Crack-free SnO2 and SiO2 films with the controlled thickness up to 1 micrometers have been prepared by the sol-gel spin coating method. Preparation conditions and microstructure of the films are described. Gas sensing elements consisting of single SnO2 thin film and multi-layered SiO2/SnO2 thin films have been prepared using this method. Comparison of sensing properties between single SnO2 thin film and multi-layered thin film sensing elements shows potential advantage for developing selective gas sensors.
