| 英文摘要 | thermochromic vo2 film is a potential material for energy-saving windows in future buildings. considering the difficulty in controlling the valence state and polymorphism during the formation of vo2 (m) film, we propose a facile and safe solution method of fabricating monoclinic (m) vo2 film directly from the newly synthesized ammonium citrato-oxovanadate(iv) compound [(nh4)(4)[v2o2(c6h4o7)(2)]center dot 2h(2)o, denoted as ca-v(iv)], as a vanadium(iv) precursor to stabilize vanadium in the 4+ valence state without utilizing v2o5 as an intermediate or complex post-treatment in vacuum. this new ambient-stable compound ca-v(iv) contains centrosymmetric dinuclear complex anions [{vo(c6h4o7)}(2)](4-), in which the carboxylate groups are coordinated to the v4+ ions in a monodentate fashion and each vanadium atom exhibits distorted octahedral geometry. with a perfect monoclinic phase, the vo2 films possessed excellent thermochromic and visible transmissive properties. accompanying a change in film thickness from 119 nm to 41 nm, the integral visible transmittance t-vis at 25 degrees c of vo2 films ranged from 38.4% to 70.0%. the maximum visible transmittance (t-max) reached 77.2% for vo2 film with a thickness of 41 nm, which shows that the phase transition of vo2 did not greatly affect the visible transmittance of the film. for the vo2 film with a thickness of 41 nm, of which the visible transmittance modulation (lambda t-vis = 2.1%) was the largest among the three samples, the solar energy modulation (delta t-sol) reached 11.3%. moreover, the transition temperature of our vo2 films was far below that of bulk vo2 (68 degrees c), and the best transition temperature was as low as 50.8 degrees c. |
