Glass articles with infrared reflectivity and methods for making the same
First Claim
1. A glass article having infrared reflectivity, the glass article comprising:
- a first glass surface, a second glass surface and a glass body, wherein the glass of the glass body extends from the first glass surface to the second glass surface;
a plurality of discrete layers of metallic silver formed in the glass body, each of the plurality of discrete layers of metallic silver having a thickness T such that 100 nm≦
T≦
250 nm, wherein each of the plurality of discrete layers of metallic silver is spaced apart from an adjacent layer of metallic silver by a spacing S such that S≦
500 nm thereby forming at least one optical cavity in the glass 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.

Abstract
Glass articles with infrared reflectivity and methods for making the same are disclosed herein. In one embodiment, glass article having infrared reflectivity includes a first surface, a second surface and a body extending between the first and second surfaces. A plurality of discrete layers of metallic silver are formed in the body creating at least one optical cavity in the body. Each discrete layer may have a thickness T such that 100 nm≦T≦250 nm and may be spaced apart from adjacent layers of metallic silver by a spacing S≦500. 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 transmits at least a portion of electromagnetic radiation incident on the glass article having a wavelength from 390 nm to 750 nm.
