Stable tin and antimony citrate complexes solution was obtained from the starting materials metal tin and antimony trioxide.The solution undergoes sol-gel transformtion when acetonitrile was added dropwise.The heat-treatment of the washed gel at different temperatures can obtain antimony doped tin oxide nanoparticles.The antimony doped tin oxide nanoparticles exhibit crystallite size shrinking,increase the specific surface area and changes of the tin oxide lattice parameters with the rise of antimony doping content.The crystalline size increases,speciflc surface area decreases with the increse of annealing temperature.The particle crystallinity shows a decrase tedency for the high antimony doping level when calcinating at high temperatures.
