FIG. 2.

(a) EDS result of individual nanowires. The atomic ratio of In, Sn, and O is estimated to be 5.5: 31.6: 62.9. The inset is the elemental mapping results along a single nanowire. (b) High resolution TEM image of ITO nanowires. The inset is the corresponding diffraction pattern.

FIG. 3.

Room temperature PL spectrum of ITO nanowires. A strong and broad emission peak is observed around .

FIG. 4.

Response and recovery characteristics of the gas sensors fabricated from ITO nanowires exposed to various concentrations of ethanol gas at . The inset is the schematic diagram of the sensing process. The depletion width on the surface is narrower in ethanol gas than that in air.
