Influences on Nanoparticle Production during Pulsed Laser Ablation
Open accessAbstract
The generation of nanoparticles using pulsed laser ablation has inherent advantages compared to conventional methods, like the purity and stability of the fabricated nanoparticle aerosols and colloids.This study addresses the influence of the pulse energy on the nanoparticle productivity and particle size during femtosecond laser fabrication of nanoparticles in air and liquids (water, hexane).Moreover, in-situ conjugation of nanoparticles in hexane is studied.The nanoparticle generation rate is 100 times higher in air compared to water.Higher pulse energies lead to higher productivity, but due to shielding effects, the optimum was determined at moderate pulse energies around 200 µJ, measured by the highest absorption intensity of the plasmon resonance of the colloids.In non-polar liquid, the in-situ conjugation of gold nanoparticles to thiol molecules during pulsed laser ablation is studied.At higher concentrations (8 mmol/l) of dodecanethiol in n-hexane solution, significant smaller nanoparticles (30 nm) and less agglomerates are generated.

High-intensity laser must initially pass through liquid medium before interacting with target metal surface, resulting in refraction of laser beam by ambient liquid media.
“The high-intensity laser must initially pass through the liquid medium before interacting with the target metal surface, which results in the refraction of the laser beam by ambient liquid media [75].”
Owing to low productivity of PLAL, attributed to higher threshold limit of ablation in liquids compared to gaseous media, adequate use of process parameters is critical.
“Owing to the low productivity of this process, attributed to the higher threshold limit of ablation in liquids compared to gaseous media, the adequate use of the aforementioned process parameters is a critical aspect of this field of research [75].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
