| 英文摘要 | In the pursuit of energy efficient materials, vanadium dioxide (VO2) based smart coatings have gained much attention in recent years. For smart window applications, VO2thin films should be fabricated at low temperature to reduce the cost in commercial fabrication and solve compatibility problems. Meanwhile, thermochromic performance with high luminous transmittance and solar modulation ability, as well as effective UV shielding function has become the most important developing strategy for ideal smart windows. In this work, facile Cr2O3/VO2bilayer coatings on quartz glasses were designed and fabricated by magnetron sputtering at low temperatures ranging from 250 to 350 °C as compared with typical high growth temperatures (>450 °C). The bottom Cr2O3layer not only provides a structural template for the growth of VO2(R), but also serves as an antireflection layer for improving the luminous transmittance. It was found that the deposition of Cr2O3layer resulted in a dramatic enhancement of the solar modulation ability (56.4%) and improvement of luminous transmittance (26.4%) when compared to single-layer VO2coating. According to optical measurements, the Cr2O3/VO2bilayer structure exhibits excellent optical performances with an enhanced solar modulation ability (ΔTsol= 12.2%) and a high luminous transmittance (Tlum,lt= 46.0%), which makes a good balance between ΔTsoland Tlumfor smart windows applications. As for UV-shielding properties, more than 95.8% UV radiation (250-400 nm) can be blocked out by the Cr2O3/VO2structure. In addition, the visualized energy-efficient effect was modeled by heating a beaker of water using infrared imaging method with/without a Cr2O3/VO2coating glass. © 2017 American Chemical Society. |
