- •
W-doped V2O5 was obtained by a molten and water quenching technology.
- •
W doped VO2 was synthesized by a facile solid reaction.
- •
The effects of thermal treatment for W doped VO2 were studied detailedly.
- •
High temperature annealing could remarkably enhance the MIT sensitivity of VO2.
- •
Electrical resistance is simultaneously sensitive in the phase transition.
