Glass articles with infrared reflectivity and methods for making the same

A glass article, the glass article comprising:

• a first surface, a second surface and a body extending from the first surface to the second surface, wherein the body is continuous with the first surface and the second surface such that the article is a single piece of glass;
• a plurality of discrete layers of metal formed in the body, each of the plurality of discrete layers of metal having a thickness T such that 100 nm≤T≤250 nm, wherein each of the plurality of discrete layers of metal is spaced apart from an adjacent layer of metal by a spacing S such that S≤500 nm thereby forming at least one optical cavity in the body, wherein:
• the glass article reflects at least a portion of electromagnetic radiation incident on the glass article having a wavelength from 800 nm to 2500 nm;
• and
• the glass article transmits at least a portion of electromagnetic radiation incident on the glass article having a wavelength from 390 nm to 750 nm;
• further comprising a layer of compressive stress extending into the body of the glass article, the layer of compressive stress having a depth of layer DOL of up to about 60 μm and magnitude of compression C≥200 MPa.
