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.
