“…172 These results suggest that the type of liquid, ablation time, energy density, and wavelength affect nanoparticle size. 176 The sol-based gold and silver nanoparticles discussed above were subsequently used to prepare thin films by spin-coating the sols, showing that it is possible to use these nanoparticles in nanocomposite films if the right solvent is chosen. 173 Clearly, producing nanoparticles from bulk noble metals with tunable properties by laser ablation represents a green alternative in the laboratory.…”

“…17 Nanoparticle systems are also of significant interest to the fuel cell community, working to increase the reaction surface for a fixed cell volume. Nanoparticle systems can be fabricated by a large range of different techniques including chemical reduction, 18 laser ablation, 19 thermal evaporation, 20 ion implantation, 21 and thermal annealing. 6,11 In this paper we investigate the physical mechanisms behind the pulsed laser melting of thin metal-on-oxide film and use this technique, entitled excimer laser nanostructuring ͑ELN͒, to produce supported metal nanoparticles, with controllable dimensions, over large area and at low macroscopic temperatures.…”

The mechanisms controlling the nanostructuring of thin metal-on-oxide films by nanosecond pulsed excimer lasers are investigated. When permitted by the interfacial energetics, the breakup of the metal film into nanoscale islands is observed. A range of metals ͑Au, Ag, Mo, Ni, Ti, and Zn͒ with differing physical and thermodynamic properties, and differing tendencies for oxide formation, are investigated. The nature of the interfacial metal-substrate interaction, the thermal conductivity of the substrate, and the initial thickness of the metal film are all shown to be of importance when discussing the mechanism for nanoscale island formation under high fluence irradiation. It is postulated that the resulting nanoparticle size distribution is influenced by the surface roughness of the initial film and the Rayleigh instability criterion. The results obtained are compared with simulations of the heat transfer through the film in order to further elucidate the mechanisms. The results are expected to be applicable to the laser induced melting of a large range of different materials, where poor wetting of substrate by the liquid phase is observed.

“…Various liquids (dimethyl sulfoxide, THF, N,N-dimethylformamide, acetonitrile) were used by Compagnini et al [109]. PLA with an Nd:YAG laser (l = 1,064 nm, t = 9 ns, F = 10 J/cm 2 ) produced Ag-NPs with dimensions varying from 7.8 nm (dimethyl sulfoxide) to~4 nm in the other fluids.…”

Lasers are widely used for material processing (cutting, drilling, cleaning, film deposition, etc.). A recent application is for nanoparticle fabrication. Pulsed laser ablation is by far the fastest and clean method to fabricate nanoparticles directly from bulk targets. For this purpose, target ablation is performed in vacuum, in gas atmosphere, or in liquids with fast (nanosecond) and ultrafast (picosecond, femtosecond) laser pulses. Mostly metal but also semiconductor and ceramic nanoparticles were fabricated. In the early stage of this technique, the main problem was the large size distribution of the produced nanoparticles. But the possibility to independently handle laser pulse characteristics (wavelength, power density, pulse duration, etc.) and the accurate control and optimization of the ambient parameters is leading to an efficient tailoring of the nanoparticle size, due also to helpful theoretical and numerical models. A review is presented of the most important studies and of the obtained results.
