Sb-doped SnO2(ATO) nanosphere was synthesized by the solvothermal route,starting with SnCl4·5H2O and SbCl3.The obtained samples were characterized by X-ray diffraction pattern,transmission electron microscopy,UV-visible transmission spectrophotometer and low-impedance surface impedance instrument.The results indicated that the 80~120 nm monodispersed ATO nanosphere was tetragonal structure,which was composed of numerous 5~10 nm ATO nanocrystallines.The Sb3+ doping content had a significant impact on optical property and electrical conductivity.With the increase of Sb3+ doping content,the transmittance in visible region and the conductivity were increased first,and then decreased.The preferable nSb/nSn molar ratio was 9:100.
