Abstract: The aqueous sol and the organic sol of SnO2 ultrafine particles (UFP) were prepared by the colloid chemistry method; The SnO2 UFP LB films prepared in dodecyl benzene sulfonic sodium (DBS) and stearic acid (SA) have been investigated. The gas sensitivities of SnO2 UFP and SnO2 were compared.

Key words: tin dioxide, ultrafine particle, LB film, gas sensitivity
