“…22 Musaev et al fabricated colloids of Ni in water by laser ablation with a nitrogen laser of 10 ns pulse duration and determined its composition using X-ray diffraction (XD). 23 However, there are no works reporting on the fabrication and characterization of colloids obtained using fs-regime laser ablation of Ni in liquids. In this work, we analyze the characteristics of structure (bare core or core−shell), configuration, number density, and size distribution of NPs generated when a fs pulse laser is used to ablate a Ni solid target in nheptane and water.…”

Synthesis of nickel (Ni) nanoparticles (NPs) suspensions was performed using a 120 femtosecond (fs) pulse laser to ablate a Ni solid target in n-heptane and water.Analysis of structure, configuration and sizing was carried out using different independent techniques such as Optical Extinction Spectroscopy (OES), Atomic Force Microscopy (AFM), Transmission Electron Microscopy (TEM) and Electron Diffraction (ED), which yield interrelated information.AFM microscopy allows determining the spherical shape and size distribution of the NPs in the obtained colloids while TEM provides knowledge about shape, structure and size distribution. ED allows identification of the different metal and metal oxide composition as well as their crystallographic phase. On the other hand, OES gives information related to size distribution, structure, configuration and composition.Interpretation of these spectra is based on Mie theory which, in turn, depends on Ni dielectric function. For NPs radii smaller than 3 nm, size-dependent free and bound electron contributions to the dielectric function must be considered. To account for the full size span, complete Mie expansion was used for optical extinction cross-section calculations. A theoretical analysis of the dependence of plasmon resonance of bare core and core-shell Ni NPs with core size and shell thickness provide insight about their spectroscopic features.For n-heptane, species like bare core Ni and hollow Ni NPs are found in the colloid, being the latter reported for the first time in this work. Instead, for water, the colloid contains hollow nickel NPs and nickel oxide in different core-shell configurations: Ni-NiO and NiO-Ni, being the latter also reported for the first time in this paper. In both cases, size distribution agrees with that derived from TEM and AFM analysis. The formation of the oxide species is discussed in terms of oxidation-reduction processes during ablation. Possible mechanisms for the formation of hollow species are proposed.

“…Particularly, the syntheses of Al and its oxide NPs by pulsed laser ablation in liquid (PLAL) was considered to be an efficient, simple, and green method [28]. In addition, this method has been widely used in the syntheses of other metal and oxide NPs [29,30,31,32,33]. However, many factors, such as the type of surrounding media [34,35,36], temperature of liquid [37,38,39], laser pulse duration [40] and fluence [41,42], the relative position of the focus and the target surface [43], adding surfactant [44], and characteristics of targets [45,46], strongly influence the ablation processes in such a manner that the composition, morphology, and particle sizes of synthesized NPs show significant differences under different conditions.…”

We analyzed the formation of the aluminum (Al) nanoparticles (NPs) with triangular shape obtained by ablating Al bulk in liquid using pulses with different durations (5 ns, 200 ps, and 30 fs) and wavelengths (355 nm, 800 nm, and 1064 nm). We report three stages of synthesis and aging of Al NPs: Formation, transformation, and stable stage. The NPs prepared by different pulses are almost identical at the initial stage. The effects of duration and wavelength of the ablation pulses on the aging of NPs are revealed. Pulse duration is determined to be essential for morphological transformation of NPs, while pulse wavelength strongly influences particle sizes. NPs produced by ultra-short pulses have smaller sizes and narrow size distribution. We demonstrate that oxidation and hydrolysis of Al in water are the results of ablation for all pulse durations and wavelengths, which also strongly modify the preferable reaction path of NPs in water, thus affecting the composition and morphology of triangle NPs. The results of modeling of the NPs generation in water due to a 50 ps laser pulse interacting with a thick Al target are presented. Water-based effects in the formation of NPs, their evolution, and solidification are considered from the mechanical and thermophysical points of view. The detailed analysis of the modeling results allowed for determination of the main mechanism responsible for the ablation process followed by the NPs formation.

“…For the case of generation of Ni NPs via laser ablation in liquids, Jaleh et al [15] reported the ablation of a pure Ni plate immersed in methanol with PVP as stabilizer agent using a high repetition Nd:YAG laser of 240 ns pulse width.

Structure, configuration, and sizing of Ni nanoparticles generated by ultrafast laser ablation in different media

et al. 2015

View full text Add to dashboard Cite

In recent years, nickel nanoparticles (NPs) have increased scientific interest because of their extensive prospects in catalysts, information storage, large-scale batteries and biomedicine. Several works on Ni NPs generation by laser ablation have appeared in the literature in the last years, using different pulsed laser regimes and different media have been published recently. In this work we analyze the characteristics of species, structure (bare core or core-shell), configuration and size distribution of NPs generated by fs pulse laser ablation over a Ni solid target in n-heptane and water. We explore the presence of NiO-Ni core-shell and hollow Ni (or air-Ni) NPs in the colloids obtained. These were experimentally characterized using AFM and TEM microscopy, as well as Optical Extinction Spectroscopy (OES). Extinction spectra were modeled using Mie theory through an appropriate modification of the complex experimental dielectric function, taking into account a size-dependent corrective term for each free and bound electron contribution. Experimental UVvisible-NIR spectra were reproduced considering a size distribution of bare core, hollow and core-shell structures NPs. In both media, Ni NPs shape and size distribution agrees with that derived from TEM and AFM analysis.
