US 10,591,652 B2 · Multi-layer coated glass substrate

Abstract

The present disclosure provides a coated glass or glass-ceramic substrate, wherein at least two coating layers are applied to each side of the substrate. Each of the coating layers comprises one or more metal oxides, and optionally a dopant. The dopant can be a halogen or post transition metal. The coated substrate can have two coating layers on each side, three coating layers on each side, or two coating layers on one side and three coating layers on the other side. The properties of each of the coating layers are adjusted so that the coated substrate can reflect infrared light in targeted wavelength ranges. The properties that can be adjusted include the number of coating layers, the coating layer thickness, the coating layer composition, the index of refraction of each coating layer, and the location of each coating layer according to their index of refraction.
