Antimony-doped tin oxide (ATO) is an important member of transparent conductive oxides (TCOs). It has been expensively studied as an alternative to indium tin oxide (ITO) due to the cheap cost. ATO is transparent throughout the visible region, while it reflects infrared light. These features enable ATO to be used as transparent electrodes, heat mirror and energy storage devices. For these applications, nanometer-sized particle are required. In this work, ATO nanoparticles were synthesized by the modified precipitation process using SbCl3, SnCl4• 5H2O and NH4OH solution. The filter cakes involving ATO hydroxide and NH4Cl as by-product were dried and heat-treated below 300oC. To remove the residual NH4Cl after heat-treating, the compounds were repeatedly washed with distilled water and dried at room temperature. ATO nanoparticles obtained by this method were characterized by means of XRD, BET, XPS, and TEM. |
