“…Meanwhile, the NPs obtained by ultrashort pulses have better uniformity in morphology and narrower particle size distribution. In addition, the XRD data exhibiting the presence of Al NPs mainly for fs ablation could be interpreted in terms of direct nanoparticle yield via phase-explosion mechanism, while for ns and ps ablation, laser–plume interaction could destroy parent ablation products until atoms and ions with the following recondensation [62].…”

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.

“…The authors attribute this antimicrobial effect to the generation of reactive oxygen species formed on the surface of Si nanoparticles during their production. Lately, an study in terms of productivity for nanosecond-laser plasma-mediated ablation regimes of these nanoparticles in water was performed [109].…”

Nanomaterials have unique properties and characteristics derived from their shape and small size that are not present in bulk materials. If size and shape are decisive, the synthesis method used, which determines the above parameters, is equally important. Among the different nanomaterial’s synthesis methods, we can find chemical methods (microemulsion, sol-gel, hydrothermal treatments, etc.), physical methods (evaporation-condensation, laser treatment, etc.) and biosynthesis. Among all of them, the use of laser ablation that allows obtaining non-toxic nanomaterials (absence of foreign compounds) with a controlled 3D size, has emerged in recent years as a simple and versatile alternative for the synthesis of a wide variety of nanomaterials with numerous applications. This manuscript reviews the latest advances in the use of laser ablation for the synthesis of silicon-based nanomaterials, highlighting its usefulness in the prevention of bacterial infection.

“…[ 23 ] Moreover, there are known different opportunities for tuning down Si nanoparticle dimensions—down to a few nanometers—through variation of ultrashort laser pulsewidth, wavelength and fluence, repetition rate‐dependent fragmentation in laser plumes, described in previous related studies on laser‐induced ablative generation of Si nanoparticles in liquids and corresponding reviews.

rather limited dangling-bond absorption of electromagnetic waves in amorphous nanosilicon, broadly variable free-carrier absorption (free-carrier concentration ≈10 17 cm −3 ) [4] in controllably doped silicon has recently brought another important modality to Si NPs, related to space-selective in situ anti-cancer hyperthermiabased therapies via near-and mid-infrared (IR) laser, or radiofrequency (RF) Joule heating. [4,6] However, to date strong Si-NP doping was realized only via minor introduction of gold, [7] since Si is rather immiscible material. [8] In contrast, n-hyperdoped Si was actively studied for the last decade as a material platform, supporting fabrication of mid-IR sensitizers for solar cells, [9] broadband active media for thin-film photovoltaics, [1] broad-band mid-IR nightvision and imaging devices for novel promising and emerging applications. The currently achieved strong (≈10 3 -10 4 cm −1 ) smooth [10][11][12][13][14] or band-engineered [15,16] mid-IR absorption in sulfur-(or selenium and tellurium [12] ) doped Si was suggested for raising solar-cell efficiency up to 49% through efficient harvesting of near-and mid-IR solar radiation. [17] Besides the donor-based band-to-band absorption, considerable free-carrier absorption via thermal ionization of shallow donor states was also reported in such Si nanoparticles (NPs), which are innovative promising light-harvesting components of thin-film solar cells and key-enabling biocompatible theranostic elements of infrared-laser and radiofrequency hyperthermia-based therapies of cancer cells in tumors and metastases, are significantly advanced in their near/mid-infrared band-to-band and free-carrier absorption via donor sulfur-hyperdoping during high-throughput facile femtosecond-laser ablative production in liquid carbon disulfide. High-resolution transmission electron microscopy and Raman microscopy reveal their mixed nanocrystalline/ amorphous structure, enabling the extraordinary sulfur content of a few atomic percents and very minor surface oxidation/carbonization characterized by energy-dispersive X-ray spectro scopy and X-ray photoelectron spectroscopy. A 200-nm thick layer of the nanoparticles exhibits near−mid-infrared absorbance, comparable to that of the initial 380-micron thick n-doped Si wafer (phosphordopant concentration ≈10 15 cm −3 ), with the corresponding extinction coefficient for the hyperdoped NPs being 4-7 orders higher over the broadband spectral range of 1-25 micrometers. Such ultimate, but potentially tunable mid-IR structured, multi-band absorption of various sulfur-impurity clusters and smooth free-carrier absorption are break through advances in mid-infrared (mid-IR) laser and radiofrequency (RF) hyperthermia-based therapies, as envisioned in the RF-heating tests, and in fabrication of higher-efficiency thin-film and bulk photovoltaic devices with ultra-broad (UV−mid-IR) spectral response.
