U.S. Pat. 4,098,956 1978 Jul; :1-5
Thin film absorber stacks consisting of an absorptive film of titanium, zirconium or hafnium suboxide, subcarbide or subnitride superposed on a reflective film of silver, aluminum or copper display spectrally selective characteristics. The absorptive film may be prepared by reactively sputtering the metal or the metal carbide in argon or other inert gas with small amounts of gas containing carbon, oxygen or nitrogen or their combinations, or by reaction of the metal film in air or other gas.
