Abstract

Solar control coatings are important in warm climates. The coating should have a high transmission of visible light, i.e. for wavelengths 0.4-0.7 µm, and reflect as much as possible of the solar radiation in the wavelength interval 0.8-2.5 µm. One concept in the design of such a film is the noble metal based multilayer¹-³. where the metal film is sandwiched between antireflecting oxide layers. Although having favourable optical performance, the presence of a thin noble metal film in the multilayer limits the stability of the configuration to the extent that they can only be used in sealed windows.
