摘要
Abstract
A novel multifunctional smart window was developed using VO2 thermochromic films with TiO2 coatings for antireflection. A strong enhancement in luminous transmittance of VO2 was calculated using either a single layer or a double layer of TiO2 for antireflection, with the double layer giving the best performance. A TiO2 (25nm)/VO2 (50nm)/TiO2 (25nm) structure, of which the film thickness has been optimized to a maximum integrated luminous transmittance (Tlum ) by calculation, was deposited on glass by sputtering in turn a V target in Ar+O2 for VO2 and a TiO2 target in Ar for TiO2! Optical properties were measured with a spectrophotometer, and the integrated solar and luminous properties were calculated based on the measured spectra. A maximum increase in Tlum by 86% (from 30.9% to 57.6%)was obtained for VO2 after double layer TiO2 antireflection coating. The deposited VO2 film on SiO2 exhibits good thermochromism with a sharp optical transition at 58.5℃, which decreased slightly to 57.5 ℃ after TiO2 coating. The proposed window is the most advanced among the similarly reported in being multifunctional with automatic solar/heat control, ultraviolet stopping, and possibly a wide range of photocatalytic functions in addition to highly luminous transmitting.关键词
