Single-step preparation of indium tin oxide nanocrystals dispersed in ionic liquids via oxidation of molten In–Sn alloys†
Abstract
Oxidation of molten In–Sn alloys was carried out in ionic liquids by heat treatment with vigorous stirring, resulting in the formation of indium tin oxide (ITO) nanocrystals. The ITO nanocrystals exhibited a plasmon peak, the peak wavelength of which was blue-shifted with an increase in the Sn fraction in ITO.
