Abstract

Titanium oxide (TiO2) and titanium nitride (TiN) multilayered films grown by pulsed laser deposition (PLD) technique have been tested as a heat mirror, which have a high transmittance in the visible region and a high reflectance in the infrared. Three layer TiO2/TiN/TiO2 heat mirrors were grown on Corning glass substrates ablating single TiN target. Switching of TiO2-to-TiN layers composition was achieved by changing gas atmosphere (oxygen-to-nitrogen). Grown TiO2/TiN/TiO2 heat mirrors are highly transparent in visible (above 60% at 525nm), opaque in infrared (10% at 2600nm) and in the range from 400 nm to 2600 nm they possess almost the same properties as films prepared using two targets: TiO2 and TiN. XPS confirms similarity of chemical composition of multilayered TiO2/TiN films prepared by single TiN and two TiO2 and TiN targets techniques. Furthermore, multifunctional self cleaning properties of TiO2/TiN heat mirrors are expected through the precise control of the composition of the top TiO2 layer operating as a photocatalyst.
