Synthesis of indium tin oxide (ITO) and fluorine-doped tin oxide (FTO) nano-powder by sol-gel combustion hybrid method

ITO and FTO nano-powders were synthesized employing a new route sot-gel combustion hybrid method using acetylene black as a fuel. The dried gels exhibited an auto-catalytic combustion behavior. ITO and FTO nano-powders with narrow size distribution were obtained at 750 degrees C. Crystal structures were examined by powder X-ray diffraction (XRD) and particle morphology as well as crystal size was investigated by scanning electron microscopy (SEM). The size of the nano-powder was found to be in the range of 16 nm to 33 nm. (c) 2006 Elsevier B.V. All rights reserved.
