Abstract

Nanoparticles (NPs) are submicron moieties made of inorganic or organic materials, which have many novel properties compared with their bulk counterparts. The CO₂ laser pyrolysis of gas- and vapor-phase reactants offers an approach for the synthesis of uniform nanoparticles. The synthesis of iron oxide-based nanomaterials by laser pyrolysis has been achieved by a handling procedure, in which the oxidation process initiates and develops inside the laser-induced reaction zone. In a second step, a more complex experimental procedure is used, in which the iron precursor is allowed to dissociate alone in the flame with a surrounding oxidizing atmosphere. XRD and TEM analyses reveal a major content of maghemite/magnetite in samples SF. The power density and the nozzle diameter influence the particle size.
