Abstract:

A glass article is provided that includes: a glass substrate comprising a thickness and a primary surface; and a textured region defined by the primary surface. The textured region comprises a plurality of sub-surface hillocks, each hillock having a top surface and a base, the base located below the primary surface of the substrate. The plurality of hillocks comprises an average lateral feature size from 0.1 .mu.m to 3 .mu.m and an average height from 5 nm to 200 nm. Further, the primary surface of the substrate is substantially planar.
