Abstract
Indium oxide ($In_2O_3$) nanowires were successfully synthesized by a simple reaction in a wet oxidizing environment at low temperature without metal catalyst. The nanowires were characterized by an x-ray diffraction (XRD), a scanning electron microscopy (SEM) equipped with an energy dispersive spectrometry (EDS), and a transmission electron microscopy (TEM). It was shown that the $In_2O_3$ nanowires were two types of morphology, uniform nanowires and nanowires containing $In_2O_3$ nanoparticles in its stem. It was found that lengths of the nanowires were ranges of several micrometers and their diameters were around $10{\sim}250$ nm. The growth direction of the nanowires was investigated and their growth mechanism is also discussed.
