“…PLA in n-hexane using the same apparatus at F = 1 Ä 200 J/cm 2 produced 10 nm Au-NPs, with a standard deviation of 60 % [101]. Also, Maciulevičius et al [102] used a ns Nd:YAG laser at 1,064 nm for ablation of gold targets in deionized water. The mean diameter of NPs varied from 20 to 45 nm.…”

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.

Fluence Threshold Behaviour on Ablation and Bubble Formation in Pulsed Laser Ablation in Liquids

et al. 2017

The ablation yield and bubble-formation process during nanosecond pulsed-laser ablation of silver in water are analysed by stroboscopic videography, time-resolved X-ray radiography and in situ UV/Vis spectroscopy. This process is studied as function of lens-target distance and laser fluence. Both the ablation yield and the bubble-cavitation process exhibit threshold behaviour as a function of fluence, which is linked to the efficiency of coupling of energy at the water/target interface. Although ablation happens below this threshold, quantitative material emission is linked to bubble formation. Above the threshold, both bubble size and ablation show linear behaviour.

“…To date, laser-assisted formation of Au nanoparticles has been investigated in numerous studies, because this metal is chemically inert [9,10] and chemical interaction of ejected NPs of Au with overheated liquid vapors is excluded. A number of studies [11−13] were devoted to the processes of generation and optical properties of Au NPs.…”

“…Until now, the effect of laser radiation on gold nanoparticles has been studied for only spherical particles, which may behave differently: undergo fragmentation [14][15][16][17]18] or agglomeration [10,19,20]. Previously, it was shown both experimentally and theoretically that the main fragmentation mechanism for nanoparticles less than 100 nm in size is the detachment of small fragments of order of 10 nm in size [21].…”

Laser-Assisted Formation of Elongated Au Nanoparticles and Subsequent Dynamics of Their Morphology under Pulsed Irradiation in Water

One-step laser generation of Au elongated nanoparticles (NPs) and their successive fragmentation and agglomeration are experimentally studied for the first time. In the present work, laser-assisted formation of Au elongated nanoparticles by ablation of a solid Au (99.99%) target in water was done using a ytterbium-doped fiber laser sources with pulse duration of 200 ns and pulse energy of 1mJ. Extinction spectrum correlating with TEM shows the appearance of absorption signal in red region and near IR-spectrum that corresponds to longitudinal plasmon resonance of electrons in elongated Au NPs. In addition, generated elongated Au nanoparticles were exposed to pulsed laser beam with various pulse energy and laser exposure time. It was found that at early stages of irradiation NPs agglomerate as the NPs chains with size of order of 1 µm long. Further laser exposure results in fragmentation of these chains. Possible processes of laser-assisted formation of elongated Au NPs in aqueous solutions of calcium chloride and their subsequent interaction with pulsed laser irradiation are discussed.
