Abstract
Well-oriented Sm-doped SnO2 nanoarrays were synthesized by a one-pot substrate-free hydrothermal route. The surface defect of the SnO2 nanorods caused by the Sm ions doped into the SnO2 lattice was investigated. The gas-sensing properties indicated that the Sm-doped SnO2 nanoarrays with optimized doping level of 1.50 at% exhibited an excellent sensing response toward isopropanol at a lower temperature. The enhancement response of the Sm-doped SnO2 nanoarrays was discussed.
