“…The laser beam's contact may have generated these particles [24]; alternately, the pressure change may have induced cavitation bubbles on the surface of the metal target. These cavitation bubbles would change to liquid bubbles without pressure changes in the neighborhood of CO 2 's boiling temperature [43]. Therefore, in our experimental conditions (5.0 MPa and 17°C), we considered the hollow particles not to be formed by cavitation pressure changes, but by direct laser beam irradiation.…”

Nickel nanoparticles with various structures were synthesized by a pulsed laser ablation process in liquid CO 2 at 17°C and 5.2 MPa. A nickel plate immersed in liquid CO 2 was used as a target. This was irradiated by a laser beam with a fundamental wavelength of 1064 nm at 2.46 mJ for 15 min. The generated particles were deposited on a silicon wafer after natural evaporation of the liquid CO 2 , and analyzed by field emission scanning electron microscopy, scanning electron microscopy with energy-dispersive X-ray spectroscopy, and transmission electron microscopy. Nickel and carbon particles with sphere-like structures or apple-shaped structures were observed. Furthermore, characteristic nickel/carbon particles with core/shell structures were also produced. The generated particles ranged in size between 5 and 350 nm in diameter, with dominant sizes under 50 nm.

“…Subsequently, the bubble collapses, leading to the synthesis of the luminescent CNPs; under the strong impact induced by the bubble collapse, CNCs obtained by restructuring move down and then are cooled by liquid. [39][40][41][42][43][44] Finally, CNCs are obtained upon PLAL (Fig. 5, the third stage).…”

“…cavitation erosion, however is under discussion. Takada et al [80] showed that the bubble collapse also seems to play a role during LAL. They found cavitation erosion pits of similar morphology as in this work and interestingly, these pits were not produced once the bubble collapse was cushioned by increasing the vapor pressure.…”
