Method for forming nanoparticle films and applications thereof
First Claim
1. A method for making a nanoparticle film comprising:
- dispersing nanoparticles in a first liquid;
adding a second liquid to the first liquid to form a nanoparticle film on top of a solution comprising the first liquid, the second liquid and the nanoparticles, wherein the second liquid has a dielectric constant that is different from a dielectric constant of the first liquid; and
contacting a substrate with the solution to deposit the nanoparticle film onto the contacted portion of the substrate.
