The influence of annealing temperature on the preparation of W- doped VO2 films is investigated in the paper. W dopant is introduced by pouring the melt V2O5 into ammonium tungstate solution. And the W- doped VO2 films are obtained via dip-coating method followed by annealing at argon atmosphere. The evolution of crystal structure, valence value of surface element, surface morphology, roughness and thermochromic performance are studied at different temperature. And different concerntration of W doped VO2 (M) films are prepared by the same method, which exhibit excellent performance. The proposed technique provides a path for fabricating W- doped VO2(M) solar modulating coatings.
