V2O5 film was first fabricated by dipping a glass slide into a V2O5 gel containing a small quantity of polytungstate sol.Then the V2O5 film was reduced in hydrogen atmosphere at 400℃ for 3 h and then a tungsten-doped VO2 thin film was prepared.The resulted film shows the characteristic green of VO2.the content of W and V is 3.212% and 64.97%, respectively.The results of the curve of resistance-temperature show that the phase transition temperature of the VO2 thin film is 40.5℃, the thermal hysteresis loop width is ΔT=11℃, amount of resistance mutation(ΔS) is 4.06 orders of magnitude.
