Abstract: Described herein are various antimicrobial glass articles that have improved resistance to discoloration when exposed to harsh conditions. The improved antimicrobial glass articles described herein generally include a glass substrate that has a low concentration of nonbridging oxygen atoms, a compressive stress layer and an antimicrobial silver-containing region that each extend inward from a surface of the glass substrate to a specific depth, such that the glass article experiences little-to-no discoloration when exposed to harsh conditions. Methods of making and using the glass articles are also described.

Abstract: Embodiments of a layered-substrate comprising a substrate and a layer disposed thereon, wherein the layered-substrate is able to withstand fracture when assembled with a device that is dropped from a height of at least 100 cm onto a drop surface, are disclosed. The layered-substrate may exhibit a hardness of at least about 10 GPa or at least about 20 GPa. The substrate may include an amorphous substrate or a crystalline substrate. Examples of amorphous substrates include glass, which is optionally chemically strengthened. Examples of crystalline substrates include single crystal substrates (e.g. sapphire) and glass ceramics. Articles and/or devices including such layered-substrate and methods for making such devices are also disclosed.

Abstract: Described herein are various antimicrobial glass articles that have improved strength and resistance to discoloration. The improved antimicrobial glass articles described herein generally include a glass substrate with a compressive stress layer and an antimicrobial silver-containing region that each extend inward from a surface of the glass substrate to a specific depth. In some embodiments, the compressive stress layer has a compressive stress at the surface of about 500 MPa or greater and the compressive stress decreases monotonically from the surface into the depth of the glass substrate. Methods of making and using the glass articles are also described and include forming a compressive stress layer and forming an antimicrobial silver-containing region by preferentially exchanging a plurality of silver cations in a silver-containing medium for a specific plurality of first cations ions in the glass substrate.
