Nanoscale powders of different iron oxide phases prepared by continuous laser irradiation of iron pentacarbonyl-containing gas precursors

Controlled manufacturing of nanoparticles by the laser pyrolysis: Application to cementite iron carbide

“…1 and details may be found in Refs. [14,15]. Iron pentacarbonyl (about 28 mm Hg (4700 Pa) vapor pressure at 25 8C) was employed as iron donor.…”

Characterization of magnetic nano-fluids via Mössbauer spectroscopy

“…The nano-powders were obtained in a flow reactor, by the IR laser irradiation (λ = 10.6 μm) of a gaseous mixture of iron pentacarbonyl and air, with C 2 H 4 as sensitizer (it is excited by the absorption of the CO 2 laser radiation), as described in details elsewhere [4]. First three samples concern the comparison of different pressure: 200 mbar for sample A, 500 mbar (B) and 600 mbar (C) at a laser power of 50 W and similar ratios for gas mixture.…”

Highly magnetic Fe2O3 nanoparticles synthesized by laser pyrolysis used for biological and heat transfer applications

“…The synthesis of iron oxide nanopowders was performed using a modified version of the previously described laser pyrolysis protocol [11,12]. An O 2 -Ar mixture (richer in oxygen than air) was used in combination with C 2 H 4 and Fe(CO) 5 vapors forming the reactive mixture.…”
