Synthesis and Characterization of Tungsten Doped Vanadium Dioxide Nanopowders by Thermolysis
摘要:
As far as we known, with white powdery tungstic acid (WPTA) used as the dopant for the first time, tungsten-doped vanadium dioxide (VO2) nanopowders were synthesized through thermolysis at low temperature. The products were characterized by XRD, TEM and DSC.When WPTA was added into V2O5 (with W/V=2 atom%), the phase transition temperature (Tc)of VO2 decreased markedly from 67.15℃ to 26.46℃ after annealing at 500℃. Such a low Tc is beneficial to the application and development of smart windows materials.
