Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of making a light extraction substrate comprising: pouring a glass melt onto a molten metal bath; applying a boron precursor over the glass melt while the glass melt has a temperature of at least 600° C. to produce a borosilicate; and applying a nanoparticle precursor over the glass melt to yield a light extraction substrate, wherein nanoparticles are present in a range of 0.1 weight percent to 20 weight percent and are at least partially embedded within the light extraction substrate. 2. The method of claim 1 , wherein the temperature of the glass melt is no more than 725° C. 3. The method of claim 1 , wherein the boron precursor is applied without a silicon precursor to produce the borosilicate. 4. The method of claim 1 , further comprising applying a silicon precursor to produce the borosilicate. 5. The method of claim 1 , wherein the applying the nanoparticle precursor forms a nanoparticle with a layer formed by the boron precursor. 6. The method of claim 5 , wherein the nanoparticle precursor comprises titanium tetrachloride.
