The VO₂‐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 VO₂@ZrO₂ 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 VO₂‐based core−shell rod structures. The thickness of ZrO₂ 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 VO₂ synthesis, their structure−property, and the application the thermochromic films for energy‐saving purposes in buildings or automobiles.

镁掺杂的VO2 @ ZrO2核壳纳米片，用于具有增强性能的热致变色智能Windows

基于VO ₂的智能窗户可以动态和可逆地调整室内太阳辐射，以减少建筑玻璃的能耗。本文报道了第一个成功制备Mg掺杂的VO ₂ @ZrO ₂核壳纳米晶体的方法，该晶体具有改进的热致变色性能以及可调谐的外观和可湿性。所达到的组合Ť _LUM的52.4％和Δ Ť_溶胶的7.1％比得上VO的最佳报告的结果₂系核-壳杆结构。ZrO ₂的厚度外壳在3到14 nm之间可调，导致表面略带疏水性，并且朝向蓝绿色和较亮的薄膜略有颜色变化。基于水热法和紫外线固化法的制备方法很容易。这项工作可能会激发VO ₂合成的未来发展，其结构性质以及将热致变色膜用于建筑物或汽车中的节能目的。
