Abstract:The W-Nb co-doped VO2 films are prepared through hydrothermal method. The effects of the Nb and W dopants are investigated respectively on the phase transition temperature (θc) and optical properties of VO2 by keeping the concentration of partner dopant at 1.0 at.%. The Nb doping induces a reduction of θc at a rate of ~ -13.0 °C per at.% Nb as Nb is less than ~1.5 at.%. For more than 1.5 at.% Nb, the θc shows a slight increase from ~23.0 °C. The W doping leads to a linear decrease of θc with a rate of ~ -17.2 … Show more
