Abstract: The object of the paper is to introduce the new phenomena of gas sensing optical transmission of SnO2:TiO2 two-dimension film of thickness less 1μm,and the phenomenon is much differentfrom the Phenomena of thickness 10pm.When the concentration of the combustible gas is lower,thetransmission spectra of the film move towards short-wave with the increasing of the gas concentration.And in higher gas concentration,the transmissivity increase with increasing of gas concentration.
