Abstract: Ion-exchanged alkali aluminosilicate glass articles with a ratio of peak compressive stress value to Young's modulus value of 14 or more. The glass articles may include Al2O3 mol %+RO mol %≥18 mol %, where RO mol %=MgO mol %+CaO mol %, and be substantially free of ZnO, SrO, BaO, B2O3, P2O5, Li2O, and K2O. The glass articles may have a peak compressive stress value in a range of 850 MPa to 1400 MPa. The glass articles are suitable for various high-strength applications, including cover glass applications that experience significant bending stresses during use, for example, cover glasses for flexible displays.

Abstract: A light-transmitting structure is disclosed. The light-transmitting structure includes a laminated glass substrate that has a core layer and a first clad layer fused to a first side of the core layer. The core layer comprises a core glass composition that is transparent and has a core refractive index nC. The first clad layer defines a first surface of the laminated glass substrate and comprises a first clad glass composition that is transparent and has a first clad refractive index nCL1 that is lower than the core refractive index nC. The light-transmitting structure further includes a plurality of interdiffusion regions that extend from the core layer and through the first clad layer to define a light-scattering surface interposed with the first surface. Each interdiffusion region comprises an interdiffusion composition that is transparent and has an interdiffusion refractive index nI that is higher than the first clad refractive index nCL1.

Abstract: A light-transmitting structure is disclosed. The light-transmitting structure includes a glass-based substrate that has a first major surface and a second major surface opposite the first major surface. The glass-based substrate comprises a first composition that is transparent and has a first refractive index n1. The light-transmitting structure further includes a plurality of surface regions fused with the glass-based substrate to define a light-scattering surface interposed with the first major surface. Each surface region comprises a second composition that is transparent and has a second refractive index n2 that is different than the first refractive index n1. The first major surface and the light-scattering surface define an interface to an ambient environment.
