Title
(EN) DEVICE FOR SYNTHESISING CORE-SHELL NANOPARTICLES BY LASER PYROLYSIS AND ASSOCIATED METHOD
(FR) DISPOSITIF POUR LA SYNTHESE DE NANOPARTICULES DE TYPE CŒUR-COQUILLE PAR PYROLYSE LASER ET PROCEDE ASSOCIE.
Abstract
(EN)
The invention concerns a device for synthesising core-shell nanoparticles by laser pyrolysis, characterised in that it comprises: - a reactor (100) comprising: •a first chamber (1) for synthesising the core, which is provided with an inlet (11) for a core precursor; •a second chamber (2) for synthesising the shell, which is provided with an inlet (21) for a shell precursor; and •at least one communication channel (3) between the two chambers (1, 2) for transmitting the core of the nanoparticles to be formed in the first chamber (1) towards the second chamber; - an optical device (200) for illuminating each of the two chambers (1, 2), said device comprising at least one laser (8) capable of emitting a laser beam (10) intended to interact with said precursors in order to form the core and the shell.
