Abstract
An inventive thin-film radiative structure is provided that includes a thin nanocomposite radiative film deposited on a substrate, the thin-film including a mix of finely dispersed phases formed by elements Mo, Si, C, O in the following atomic percentage terms: Mo from 10 to 20%, Si from 15 to 30%, C from 15 to 60%, O from 0 to 20%, and one or a combination of elements Ti, Zr, Hf, Cr, Si, Al, and B in percentage terms of 0-30%. The thin-film radiative structure has an emissivity of more than 0.7 for wavelengths 2-20 μm at temperatures above 500° C., and a sheet resistance of between 10 and 150 Ohm/sq. The radiative film may be used as a thermoresistive element in thin-film infra-red thermal emitters and infra-red heaters, and in nondispersive infrared sensors (NDIR) and photo-acoustic gas sensors, and as the radiative element in IR signaling devices.
