摘 要：La and Sb doped SnO2 conductive nanoparticles were synthesized by the complexation-coprecipitation method with Sn, Sb2O3 and La2O3 as the raw materials. Thermal behavior, crystal phase, and structure of the synthesized conductive nanoparticles were characterized by TG/DTA/DSC, FTIR, XRD and TEM techniques, respectively. The resistivity of the synthesized conductive nanoparticles was 0.07 Ω·cm; TG/DSC/DTA curves showed that the precursors lost weight completely before 800 ℃; FTIR spectrum showed that the vibration peak were wide peak in 731.4～586.4 cm-1. The La and Sb doped SnO2 conductive nanoparticles had intense absorption in 4000～2500 cm-1; La and Sb doped SnO2 had a structure of tetragonal rutile; complex doping was achieved well by complexation-coprecipitation method and was recognized as replacement doping or caulking doping; TME showed that the particles were weakly agglomerated, and the size of the particles calcined at 800 ℃ ranged approximately from 10 to 20 nm.
