Abstract
A structure can comprise a substrate and a composite coating. The composite coating can be formed over a surface of the substrate. The composite coating can include one or more nanoparticles within an oxide matrix. The nanoparticles can be formed of a temperature-dependent Mott insulator having a phase transition temperature. At a temperature below the phase transition temperature, the composite coating can transmit light in a first wavelength range, and at a temperature above the phase transition temperature, the composite coating can block light in the first wavelength range. For example, the structure can be used as a smart 10 window to help regulate heating of building interiors due to solar radiation. The composite coating can be formed via a short-duration, high-temperature heating pulse, for example, at least 1500 K for less than 60 seconds.
