Abstract

A nanoparticle coater includes a housing; a nanoparticle discharge slot; a first combustion slot; and a second combustion slot.

First claim

What is claimed is:

1. A nanoparticle coater, comprising:
a housing, the housing including;
a nanoparticle discharge slot connected to a nanoparticle source and a carrier fluid source for depositing nanoparticles from the nanoparticle source directly onto a glass ribbon located in a float bath;
a first combustion slot; and
a second combustion slot, wherein the nanoparticle discharge slot, the first combustion slot and the second combustion slot extend through the housing at separate locations from each other,
wherein the nanoparticle discharge slot is located between the first combustion slot and the second combustion slot, and
wherein the first combustion slot is configured to direct a first flame onto the glass ribbon at a location upstream from the nanoparticle discharge slot as the glass ribbon moves past the nanoparticle coater, wherein the first flame increases the temperature of the glass ribbon and lowers the viscosity of the glass ribbon to a desired amount prior to deposition of the nanoparticles onto the glass ribbon and wherein the second combustion slot is configured to direct a second flame onto the glass ribbon at a location downstream from the nanoparticle discharge slot as the glass ribbon moves past the nanoparticle coater, wherein said second flame is separate from said first flame and such that said first flame and said second flame heat the surface of the glass ribbon at locations that are separate from one another and wherein said second flame smooths over the surface of the glass ribbon after deposition of the nanoparticles, wherein the first combustion slot is connected to a first fuel source and a first oxidizer source, and the second combustion slot is connected to a second fuel source and a second oxidizer source, and wherein fuel and oxidizer flow rates for the first combustion slot and the second combustion slot are configured to be controlled separately and independently from each other and from nanoparticle source and carrier fluid flow rates.

2. The nanoparticle coater of claim 1 , wherein the nanoparticle source comprises metal oxide nanoparticles.

3. The nanoparticle coater of claim 1 , wherein the nanoparticle source comprises luminescent and/or phosphorescent nanoparticles.

4. The nanoparticle coater of claim 1 , wherein the first fuel source comprises natural gas.

5. The nanoparticle coater of claim 1 , wherein the first oxidizer source comprises oxygen.

6. The nanoparticle coater of claim 1 , wherein the first fuel source is different than the second fuel source.

7. The nanoparticle coater of claim 1 , wherein the first oxidizer source is different than the second oxidizer source.

8. The nanoparticle coater of claim 1 , wherein a plurality of nanoparticle coaters are used in series to deposit nanoparticles onto a glass ribbon to create different regions or bands of nanoparticles.

9. The nanoparticle coater of claim 1 , wherein the first combustion slot is configured to be selectively activated to control a depth of penetration of the nanoparticles into the glass ribbon.
