Studies on the optoelectronic properties of the thermally evaporated tin-doped indium oxide nanostructures

► An accurate composition of ITO nanorods was synthesized directly by one-step thermal evaporation. ► The optoelectronic properties of ITO nanorods are better than it of In2O3 nanorods, nanotowers due to doping tin. ► The electrical resistivity of In2O3 nanorods is 20 times higher than it of ITO nanorods. ► The electrical resistivity of In2O3 nanorods is 10 times higher than it of In2O3 nanotowers. ► The CL spectrum of ITO nanorods causes a blue-shift.
