on line Monitoring of composite nanoparticles synthesized in a pre industrial laser pyrolysis reactor using laser induced breakdown spectroscopy
Spectrochimica Acta Part B: Atomic Spectroscopy, 2008Co-Authors: Tanguy Amodeo, Benoît Guizard, François Ténégal, Hicham Maskrot, Christophe Dutouquet, Olivier Le Bihan, Emeric FrejafonAbstract:Abstract Laser-Induced Breakdown Spectroscopy (LIBS) was employed for On-Line and real time process Monitoring during nanoparticle production by laser pyrolysis. Laser pyrolysis has proved to be a reliable and versatile method for nanoparticle production. However, an On-Line and real time Monitoring System could greatly enhance the process optimization and accordingly improve its performances. For this purpose, experiments aiming at demonstrating the feasibility of an On-Line Monitoring System for silicon carbide nanoparticle production using the LIBS technique were carried out. Nanosecond laser pulses were focused into a cell through which part of the nanoparticle flux diverted from the production process was flowed for LIBS analysis purposes. The nanoparticles were vaporized within the laser-induced plasma created in argon used as background gas in the process. Temporally-resolved emission spectroscopy measurements were performed in order to monitor nanoparticle stoichiometry. Promising results were obtained and On-Line Si/Cx stoichiometry was successfully observed. These results put forward the possibility of real time correction of the nanoparticle stoichiometry during the production process.
