摘要： A device for synthesising core-shell nanoparticles by laser pyrolysis is provided. The device includes a reactor having a first chamber for the synthesis of the core, provided with an inlet for a core precursor, a second chamber for the synthesis of the shell, provided with an inlet for a shell precursor, and at least one communication channel between the two chambers to transmit the cores of the nanoparticles intended to be formed from the first chamber towards the second chamber. The device also includes an optical device to illuminate each of the two chambers, the device comprising at least one laser capable of emitting a laser beam intended to interact with the precursors to form the core and the shell. The device further includes at least a shell precursor inlet channel, one end of which is in the form of a distribution chamber surrounding the communication channel between the two chambers of the reactor, said distribution chamber being further provided, on its inner periphery, with at least one opening leading inside said communication channel.
