In this study, a multilayer thin film of ITO/VO2/TiO2 was investigated for simultaneous control of the solar and thermal spectra with potential application as an energy-efficient coating for windows in built environments. The functions for these layers were: low emissivity, thermochromism, and anti reflectance in the visible region. Films were deposited using reactive magnetron sputtering and characterized with scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, UV-vis-NIR spectrophotometry, and Fourier transform infrared spectroscopy. The results demonstrate that relatively high luminous transmittance, low emissivity, and favorable thermochromism can be achieved for a film with a transition temperature centered at 52 degrees C with a hysteresis width of 18 degrees C. This shows that an advancement of the previous state of the art can be made by restricting the Scherrer grain size of the VO2 layer to 92 nm. (C) 2016 Elsevier B.V. All rights reserved.
