摘要: This paper presents results from a study of gas sensors produced using laser ablated nanocrystalline metal oxides. The devices have been tested for their potential use as NO2 detectors with particular emphasis on cross sensitivity to NO. Subsequently, these SnO2 are compared the sensing capabilities other made In2O3 and WO3 prepared via similar route. investigation focussed studying at low concentration levels view environmental monitoring applications. Very high sensitivities together fast response times observed both materials.
