The sol-gel process has been used to prepare osmium doped tin oxide thin films. The energy gap and refractive index were evaluated from optical measurements. Electrical characterization has been performed in a controlled atmosphere in order to investigate the influence of methane on the electrical conductance. New results have been obtained that make tin oxide doped with osmium a very interesting material for fabrication of low power consumption sensors for methane detection. © 1998 American Institute of Physics.
