Abstract

The technique of laser pyrolysis of silane gas appears as a very flexible tool for the production of gram quantities of Si nanoparticles. In order to decrease particle size, we followed two complementary strategies: addition of a reaction sensitizer; introduction of a "quenching" collection system, at variable distance with respect to the laser beam. So close control of the average primary particle size was achieved, whereas a complex effect on the aggregation state of nanoparticles was found. The effect of the synthesis conditions on the chemical composition and on the luminescence emission of the collected nanopowders will also be discussed.
