Abstract
Methods of coating core materials by providing target materials and core materials; ablating the target materials to form ablated particulate target materials; and coating the core materials with said ablated particulate target materials; wherein the method is performed at a pressure of about 10 Torr or higher. Methods of coating particles with nanometer to multiple nanometer thick coatings in atmospheric pressure, and using pneumatic fluidization, are also provided.
Claims21
A fluidized bed coating apparatus for coating core particles by ablation of a coating material, comprising:
- (a) a coating chamber configured to receive core particles as a substrate intended to be coated, comprising at least one wall;
- (b) a transparent window located within the wall of the coating chamber;
- (c) a matrix target located within the coating chamber, comprising a coating material;
- (d) a gas distributor configured to fluidize the core particles within the chamber by passing gas flow through the core particles;
- and
- (e) a laser configured to ablate the coating material by directing energy through the transparent window toward the matrix target,
- wherein the apparatus is configured to coat the core particles at a pressure higher than 10 Torr.
