Abstract
The invention relates to a light extraction substrate having a light extraction layer. The light extraction layer includes boron, boroate, and/or borosilicate as well as nanoparticles.
Claims23
A light extraction substrate comprising a glass, the glass comprising a first surface and a second surface;
- and a light extraction layer over the first surface, wherein the light extraction layer comprises borosilicate and nanoparticles, and wherein the light extraction layer is at least partially embedded into the glass such that at least a portion of the borosilicate and the nanoparticles are integrated into the glass below the first surface.
(canceled)
An organic light emitting device comprising:
- a substrate having a first surface and a second surface;
- a light extraction layer over the first surface of the substrate, wherein the light extraction layer comprises a borosilicate layer;
