Abstract
ITO thin films were prepared by a dip - coating method using a aqueous solution containing In and Sn elements. Structure
composition and surface morphology of the thin films were examined by XRD
XPS and SEM respectively. The gas sensitive properties of the thin films were investigated and the results indicated that the thin films had a good selectivity and a high sensitivity to NO
2
and their resistances were very steady.
