Abstract
Disclosed is a method for producing particles, including the steps: introducing, into a reaction chamber, at least one reaction flow including a first chemical element and propagating in a direction of flow; projecting a radiation beam through the reaction chamber, intersecting each reaction stream in one interaction area per reaction flow, to form, in each reaction flow, particle cores including the first chemical element; and introducing, into the reaction chamber, a second chemical element interacting with each reaction flow to cover the particle cores with a layer including the second chemical element. Each reaction flow is preferably free of any agent oxidizing the first chemical element. Preferably a ratio of one atom of the second element is introduced per unit of time for at least two atoms of the first element introduced per unit of time. The second element is preferably introduced in at least one confined flow.
