Abstract: A textured glass substrate along with articles comprising a textured glass substrate and methods of making are provided. The substrates retain the mechanical and optical properties of the untextured glass, while the process provides a reliable and low cost, easy scale up method. The resulting glass substrates are of particular use for light extraction in organic light emitting diode structures.

Abstract: A method of making strengthened glass articles that includes: providing an article comprising ion-exchangeable alkali metal ions and first and second primary surfaces; etching the first primary surface with an etchant having a pH of less than 7 to form an etched first primary surface; forming an anti-glare surface integral with the second primary surface after masking the first primary surface with a masking film; removing the masking film; providing a first ion-exchange bath comprising ion-exchanging alkali metal ions, each having a larger size than the size of the ion-exchangeable alkali metal ions; and submersing the article in the first bath to form a strengthened article. Further, the strengthened article comprises a compressive stress region extending from the etched first primary surface and the second primary surface to first and second selected depths, respectively. The etching step can be conducted in an etchant-containing bath or with a sponge-rolling apparatus.

Abstract: Anti-glare glass-based articles and methods of processing a glass based article to reduce warp are disclosed. A method for processing a glass-based article includes etching a first surface of the glass article to create a first anti-glare surface having a plurality of first anti-glare features and etching a second surface of the glass-based article to create a second anti-glare surface having a plurality of second anti-glare features. At least one of a length, a width, and a diagonal of the glass-based article is greater than or equal to 500 mm. A difference of warp between a first warp value before etching the first surface and the second surface and a second warp value after etching the first surface and the second surface is less than or equal to 0.15 mm across each of one or more 500 mm intervals of length, width, or diagonal of the glass-based article.

Abstract: A glass article is provided (and methods of making the same) that includes: a glass substrate comprising a thickness and a first primary surface; and a porosity-graded layer that extends from the first primary surface of the substrate to a first depth within the substrate. The first depth is from about 250 nm to about 3000 nm. The porosity-graded layer comprises a plurality of pores having an average pore size from about 5 nm to 100 nm. The article comprises a single-side average reflectance of less than 9% at an incident angle of 60 degrees across a spectrum from 350 nm to 2000 nm. Further, the porosity-graded layer comprises a surface porosity at the first primary surface and a bulk porosity at the first depth, the surface porosity greater than the bulk porosity.

Abstract: Anti-glare glass-based articles and methods of processing a glass based article to reduce warp are disclosed. A method for processing a glass-based article includes etching a first surface of the glass article to create a first anti-glare surface having a plurality of first anti-glare features and etching a second surface of the glass-based article to create a second anti-glare surface having a plurality of second anti-glare features. At least one of a length, a width, and a diagonal of the glass-based article is greater than or equal to 500 mm. A difference of warp between a first warp value before etching the first surface and the second surface and a second warp value after etching the first surface and the second surface is less than or equal to 0.15 mm across each of one or more 500 mm intervals of length, width, or diagonal of the glass-based article.
