Abstract
A method is provided for producing particles, such as nanoparticles. The method includes introducing an ionic liquid into a deposition chamber, and directing one or more material toward or depositing one or more materials onto the ionic liquid by physical vapor deposition to form nanoparticles in the ionic liquid.
Claims25
A method for producing particles, comprising the sequential steps of:
- spreading an ionic liquid over a surface of a substrate, thereby forming an ionic liquid coated substrate,
- introducing said ionic liquid coated substrate into a deposition chamber;
- and
- moving said ionic liquid coated substrate under a physical vapor deposition target, thereby directing one or more materials onto the ionic liquid of the ionic liquid coated substrate by physical vapor deposition, and providing particles in the ionic liquid of the ionic liquid coated substrate.
