In　this　paper,　indium　doped　SnO　2　nanorods　and　nanowires　have　been　prepared　by　the　molten　salt　method,　and　the　effects　of　indium　doping　concentration　on　the　morphology　and　electrical　properties　of　one-dimensional　(1D)　SnO　2　nanostructures　have　been　studied.　It　is　found　that　indium　doping　concentration　can　affect　the　epitaxial　growth,　morphology　and　the　electrical　conductance　of　1D　SnO　2　nanostructures.　It　is　also　found　that　the　element　made　by　using　6　mol%　indium　doped　SnO　2　nanorods　responds　to　nitrogen　gas.　©　Science　China　Press　and　Springer-Verlag　Berlin　Heidelberg　2012.
