Thermochromism of sputter-deposited vanadium oxyfluoride coatings

Thermochromism offers interesting possibilities for controlling the radiative throughput through windows, as well as for numerous other applications.1-3 The state of the art is summarized for organic and inorganic thermochromic materials in the previous two chapters by Day and by Jorgenson and Lee. The purpose of this brief paper is to point at the potential and prospects of using sputter-deposited vanadium oxyfluoride coatings.4
