Complexation-Coprecipitation Synthesis and Properties of Lanthanum and Antimony Doped SnO<,2> Conductive Nanoparticles
La and Sb doped SnO<,2> conductive nanoparticles were synthesized by the complexation-coprecipitation method with Sn, Sb<,2>O<,3> and La<,2>O<,3> 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 0.07Ω·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 731.4~586.4cm<-1>. The La and Sb doped SnO<,2> conductive nanoparticles had intense absorption in 4000~2500cm<-1>; La and Sb doped SnO<,2> 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 20nm.
