Paper Abstract

Calculations of the transmittance and reflectance between 0.35 pm and 10 pm of semitransparent films of TiN, ZrN and HfN have been performed. The calculations are based on recently reported optical constants. They show that these compounds can be used as transparent heat-mirrors. These materials show considerable higher emittance than the noble-metals but comparable or higher visible transmittance. It is also shown that the transmittance can be increased by the technique of induced transmission.
