Selective radiative cooling with MgO and/or LiF layers
Abstract
A material for a wavelength-selective radiative cooling system, the material comprising an infrared-reflective substrate coated with magnesium oxide and/or lithium fluoride in a polycrystalline form. The material is non-absorptive for short wavelengths, absorptive from 8 to 13 microns, and reflective at longer wavelengths. The infrared-reflective substrate inhibits absorption at wavelengths shorter than 8 microns, and the magnesium oxide and/or lithium fluoride layers reflect radiation at wavelengths longer than 13 microns.
