Laser-generated iron-gold-particles: Particle properties in dependence of synthesis parameters
The pulsed laser ablation in liquid (PLAL) is a simple, green, and cost-effective method for the synthesis of bimetallic nanoparticles. On the basis of this method various material combinations within one particle are made possible, thus creating particles with unique physical and chemical properties. Here, we investigate the influence of different laser pulse durations i.e., short (pico-second) and long (nano-second), on the structure of the Fe-Au particles. Detailed characterisation of the Fe-Au particles prepared with two lasers gave interesting results in terms of yields of four different particles structures, metal compositions, size distributions and magnetic properties. Interestingly, here in this work, the pico-second laser produced particles with a broad monomodal (70 ± 30 nm) size distribution. Contrary, the bimodal size distribution (7 nm and ∼ 1 μm) was produces with the nano-second laser. Since Fe-Au particles were formed in liquid, two additional laser-based processes could take place, that is: pulsed laser melting in liquid (PLML) and pulsed laser fragmenting in liquid (PLFL). Based on these findings, we propose particle formation mechanisms for the pico- and the nano-second laser.
期刊介绍:
Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
