Doped and undoped ITO nanowires

Sn-doped In2O3 (ITO) nanowires have been prepared by carbon-assisted synthesis starting with a powdered mixture of the metal nitrates or with a citric acid gel formed by the metal nitrates. Copious quantities of nanowires could be grown on gold-sputtered Si substrates. The ITO nanowires were single-crystalline and optically transparent. In2O3 nanowires doped with both Sn and Zn can also be prepared by the procedures described.
