Preparation and Properties of Gd and Sb Doped SnO₂ Conductive Nanoparticles

Abstract:

Gd and Sb doped SnO2 conductive nanoparticles were prepared by the coprecipitation method with SnCl4•5H2O, SbCl3 and Gd2O3 as the raw materials. The crystal phase and structure of the prepared conductive nanoparticles were characterized by FTIR, XRD and TEM techniques, respectively. The resistivity of the prepared conductive nanoparticles was 0.29 Ωcm; FTIR spectrum showed that the vibration peak are wide peak in 723 cm-1～451cm-1, the Gd and Sb doped SnO2 conductive nanoparticles have intense absorption in 4000 cm-1～1600 cm-1; Gd and Sb doped SnO2 have a structure of tetragonal rutile; complex doping is achieved well by coprecipitation method and is recognized as replacement doping or caulking doping; TME shows that the particles were weakly agglomerated, the size of the particles calcined at 800°C ranged approximately from 10 to 30 nm.
