PLANT FOR NANOSTRUCTURE SYNTHESIS BY LASER PYROLYSIS FROM SOLID PRECURSORS

摘要

The invention relates to a plant for the synthesis of nanostructures from solid precursors using laser pyrolysis. According to the invention, the plant consists of a system () for the supply of gaseous precursors containing a supporting gas (), the reactive precursors (), a confinement gas (), the said gases being controlled by a flow rate mass control unit (), a system () for vapour generation which comprises a dual system for thermostating the vaporizing enclosure and the heat source, respectively, monitored and controlled by a system comprising a temperature control unit (), a pressure control unit () and an integrated monitoring system () which allows harmonization of pressure, temperature and gas flow-rate parameters, a heated transfer channel () through which the reactive precursors are processed or not, depending on the synthesis requirements, an injector () which injects the precursors into a reaction chamber where they cross a laser beam generated by a generator, included in a compartment () together with an optical system () for transferring and processing the beam and a compartment () comprising the reaction chamber and a system () for recovering the powders resulting from the synthesis.
