Nanostructured glass surfaces enable new and innovative applications for glass substrates. These nanostructures enable trapping as well as extraction of light. They affect the propagation of light such that it scatters and is trapped or extracted based on the index of the propagation media. The diffusive scattering component as opposed to the specular component is what enables the trapping and extraction. Often smooth surfaces are required for growing semiconductor thin films. Scattering sites beneath these surfaces can significantly enhance the optical performance of these films. Example devices utilizing these substrates include organic light-emitting diodes (OLED) displays, OLED lighting components, and microelectromechanical systems reflective displays. We demonstrate methods to fabricate these substrates using nanoparticle deposition processes. Important parameters of these nanoparticles and their agglomerates include both size and refractive index. We characterize these substrates using atomic force microscopy and scanning electron microscopy microscopy, and we simulate their optical properties using optical scattering models. © 2015 The American Ceramic Society and Wiley Periodicals, Inc.
