OPTICAL GEOMETRY METHODS FOR NANOPOWDER SYNTHESIS BY CO/MICROMETRIC LASER PYROLYSIS, WITH AND WITHOUT SOLID PRECURSOR

摘要

The invention relates to a nanopowder synthesis method using CO/micrometric laser pyrolysis, with and without solid precursor. According to the invention, the method consists in that a laser radiation source (SRL) emits a raw laser beam which is then processed in some beam transport and processing compartments, to bring it to the geometrical and optical parameters preset for the reaction zone, where, depending on the radiation source (SRL), the transport may be performed by some reflective mirrors or by fibre, the beam processing being performed by means of some optical assemblies, depending on the wavelength, ensuring a double pass through the reaction chamber (CR) which also communicates with a compartment for processing some precursors, the synthesis products being collected in a nanoparticles/nanostructures recovery compartment.
