Abstract

     The realization of the so-called "greenhouse effect" or the "inverse greenhouse effect" requires the fabrication of devices that have a spectral selectivity. Silicon monoxide deposited onto aluminium-coated glass substrate was prepared and tested. The optical properties of the coating were measured. The temperature of a black body covered with this multilayer coating was calculated. The black body temperatures decrease of about 28 K in the case of SiO coating is facing the absorber.

 

Keywords: inverse green house effect; cooling; optical properties; SiO/Al coatings.
