Summary: | Abstract
The VO
2
‐based smart windows can dynamically and reversibly adjust the indoor solar irradiation to reduce the energy consumption for building glasses. This paper reports the first successful preparation of Mg‐doped VO
2
@ZrO
2
core−shell nanocrystals with promoted thermochromic performance as well as tunable appearance and wettability. The achieved combination of
T
lum
of 52.4% and ∆
T
sol
of 7.1% is comparable to the best‐reported results of VO
2
‐based core−shell rod structures. The thickness of ZrO
2
shell is tunable between 3 and 14 nm, resulting in a slightly hydrophobic surface and a slight color change toward blue‐green and brighter produced films. The preparation method based on hydrothermal and UV‐curing methods is facile. This work may inspire future development of VO
2
synthesis, their structure−property, and the application the thermochromic films for energy‐saving purposes in buildings or automobiles. |
