“…Compared to the initial composition of Vitreloy 1, the element O is additional, and its atomic ratio exceeds 20%, which most probably stems from the confined water or its vapor. This result demonstrates that the ablation products experience an oxidation reaction due to the high-temperature-and-pressure (HTP) environment during the underwater PLA [33].…”

In this paper, we perform a single nanosecond pulse laser ablation of a Zr-based metallic glass (Vitreloy 1) target in water. The violent ejection of high-temperature ablation matter is observed from the target by means of explosive boiling, which is accompanied by a formation of cavitation bubble. These ablation products entered the water include a rich variety of nanoparticles that can be classified into three different types: full amorphous, amorphous-crystalline composite, and polycrystalline. The amorphous nanoparticles have relatively smaller sizes and a uniform elemental distribution. The latter two types of nanoparticles exhibit a unique core-shell feature with an obvious compositional segregation. It is proposed that the diversity of the nanoparticles closely depends on the different pathways that they enter the water: directly before the bubble formation or via the bubble, in which the cooling rate and the glass-forming ability of ablation products are two competing factors. A typical Zr 41.2 Ti 13.8 Cu 12.5 Ni 22.5 Be 10.0 (Vitreloy 1) metallic glass was used as the target material, because of its good glass-forming ability (GFA) and relatively high thermal stability [27]. The surfaces of the targets (10 mm × 10 mm × 2 mm) were polished to remove oxides. The amorphous structure of the targets was confirmed by both X-ray

“…In addition, the crystal lattice planes (‐220), (11‐3) and (‐111) of monoclinic structure of CuO phase corresponding to the interplanar spacing of 0.13 nm, 0.15 nm and 0.27 nm respectively were also observed. The presence of single phase CuO NPs can be attributed to the high chemical reactivity of Cu atoms with the surrounding medium at high temperature during prolonged laser ablation process . The presence of both Cu/CuO phases indicates that the synthesised NPs are polycrystalline in nature which is in line with the obtained UV‐Vis spectra of the sample.…”

Solvents Effect on the Morphology and Stability of Cu/CuO Nanoparticles Synthesized at High Fluence Laser Ablation

Cu/CuO NPs were synthesized by ablating Cu target using nanosecond Nd:YAG pulsed laser operating at 1064 nm with 8 ns pulse duration in three different solvents viz: ethylene glycol (EG), deionized water (DI) and ethanol (Eth). The effects of these three solvents at high laser fluence of 40 J/cm 2 was investigated to study the stability and morphology of nanoparticles using microscopic and spectroscopic techniques. The morphology of these nanoparticles are dependent on the physical properties of solvents (like viscosity, conductivity, polarity and enthalpy) used in laser ablation. EG and DI shows tadpole and necklace like structure whereas in Eth hollow structures were observed. The crystallinity of nanoparticles were confirmed by HRTEM, SAED and XRD analysis. In all the three solvents the characteristic absorption and emission peaks of Cu and CuO nanoparticles were observed and have been elaborately discussed in this paper. In addition, the detailed growth kinematics of nanoparticles involved in the process of laser ablation technique have been highlighted.

“…The effects of ablation time on the structure and optical properties of the grown copper oxide nanoparticles were investigated. The results of transmission electron microscopy images showed that the synthesized nanoparticles were spherical with an average size of 24-37 nm [273]. In 2018, S. Yu et al presented a new strategy for producing TiO 2 or TiO 2 /carbon microstructures using the DLW process.…”

Micro/nano structures have unique optical, electrical, magnetic, and thermal properties. Studies on the preparation of micro/nano structures are of considerable research value and broad development prospects. Several micro/nano structure preparation techniques have already been developed, such as photolithography, electron beam lithography, focused ion beam techniques, nanoimprint techniques. However, the available geometries directly implemented by those means are limited to the 2D mode. Laser machining, a new technology for micro/nano structural preparation, has received great attention in recent years for its wide application to almost all types of materials through a scalable, one-step method, and its unique 3D processing capabilities, high manufacturing resolution and high designability. In addition, micro/nano structures prepared by laser machining have a wide range of applications in photonics, Surface plasma resonance, optoelectronics, biochemical sensing, micro/nanofluidics, photofluidics, biomedical, and associated fields. In this paper, updated achievements of laser-assisted fabrication of micro/nano structures are reviewed and summarized. It focuses on the researchers’ findings, and analyzes materials, morphology, possible applications and laser machining of micro/nano structures in detail. Seven kinds of materials are generalized, including metal, organics or polymers, semiconductors, glass, oxides, carbon materials, and piezoelectric materials. In the end, further prospects to the future of laser machining are proposed.
