Conducting antimony-doped tin oxide (ATO) nanoparticles were prepared by a nonaqueous solution route, using benzyl alcohol as both the oxygen source and the solvent, and tin tetrachloride and Sb(III)/Sb(V) compounds as tin and antimony, respectively. This reaction produced non-agglomerated crystalline particles 3-4 nm in size, which can be easily redispersed in high concentrations in a variety of solvents to form stable transparent colloidal solutions without any stabilizing agents. The introduction of Sb dopant dramatically increased the particle conductivity, which reaches a maximum of 1.10(-4)S cm(-1) for 4% of Sb. Annealing in air at 500oC further improves the conductivity to 2.10(2)S cm(-1).
