	abstract = {A simple and cost effective sol-gel process for producing vanadium dioxide thin films was developed via thermolysis of V2O5{\textperiodcentered}nH2O (n ≈ 2) VV precursors prepd. by dissolving vanadium powder or V2O5 powder in 30\% hydrogen peroxide solns. After spin-coating on fused silica substrates and annealing at 750{\textdegree} in vacuum, without any intermediate gas reducing step, the major phase VO2(M, monoclinic phase) was found in both of the films based on V-H2O2 and V2O5-H2O2 precursor, exhibiting large transmittance changes (> 40\%) in the IR region (> 2000 nm) and small hysteresis loop width (< 5{\textdegree}) which were comparable to reported epitaxial VO2 films. The two films have similar metal-to-insulator transition temp. τC = 62.5{\textdegree}, lower than the classical value of 68{\textdegree} for VO2 thin films. In addn., the method enables simple doping, as found for 0.56 at.\% W-doped VO2 films. This intrinsically simple soln. process followed by one-step annealing makes it potentially useful in smart window applications. [on SciFinder(R)]},
