Abstract
Nanosized tin-doped indium oxide (ITO) with different phase formation and morphologies has been successfully synthesized by two different chemical methods: combustion synthesis from the aqueous tin and indium nitrate solution containing urea as the fuel and hydrothermal treatment of the solution with the urea as the mineralizer. The sub-micrometer ITO nanoclusters with stratified morphology were obtained by calcining the obtained precursor from combustion process at 600°C for one hour. However, by utilizing urea as the mineralizer during hydrothermal treatment, the obtained ITO powders exhibit a composite consisting of spheres and rods after calcining at 600°C for one hour. Both of the processing routes yield a two-phase mixture consisting of rhombohedral and cubic forms of ITO.
