A new method, Fe/Mg co-doping, is proposed for the first time to optimize thermochromic VO2 and the promising performance of VO2-based smart windows for practical applications is successfully achieved.
Index-tunable anti-reflection SiO2 coatings prepared on the surface of VO2 films by sol–gel dip-coating technique to enhance the visible and infrared transmittance of SiO2/VO2 films.
