| 英文摘要 | for decades, scientists have devoted themselves to developing vanadium dioxide (vo2) films for thermochromic smart windows, but there remains a major challenge to their large-scale implementation owing to their limited solar modulation ability. here, we show a new method for improving their solar modulation ability via increasing optical switching in the visible region upon phase transition. vo2-based composite films that exhibited reduced haze (haze(555) (nm) down from 46.5% to 2.2% @rt), improved luminous transmittance (up from 9.6% to 38.5% @rt) and enhanced solar modulation ability (delta t-sol up from 8.1% to 16.9% @rt) have been fabricated by a convenient and controllable approach. with this method, the mean sizes of vo2 particles can be easily tuned from 150 nm to 40 nm by varying the preparation parameters. via a combination of the optical transmittance spectrum and mie calculations, we first observed the behavior of optical switching in the visible region upon phase transition, which is size-dependent. moreover, distinctive size effects on variations in the band gap energy and specific interband transitions were studied based on the absorption spectra of vo2 composite films. |
