Understanding the growth of amorphous SiO₂nanofibers and crystalline binary nanoparticles produced by laser ablation

Abstract

The pulsed-laser evaporation synthesis of silica nanofibers and crystalline binary nanoparticles is investigated in detail. By careful adjustment of the synthesis parameters one can tailor the product to form high yield nanofibers or binary nanoparticles. Some control on their diameters is also possible through the synthesis parameters. Oxidation of the nanofibers occurs upon exposure to air after the reaction.

Generating Silicon Nanofiber Clusters from Grinding Sludge by Millisecond Pulsed Laser Irradiation

“…There is an increasing requirement for silicon nanomaterials such as nanoparticles, nanofibers, and nanowires in the LiB industries [4,[7][8][9]. These nanomaterials are currently produced from high-purity silicon powders/wafers by vapor-liquid-solid methods [10,11], or thermal/laser evaporation methods [12][13][14][15][16]. These methods require expensive…”

Submicrometer Hollow Bioglass Cones Deposited by Radio Frequency Magnetron Sputtering: Formation Mechanism, Properties, and Prospective Biomedical Applications

“…To achieve this goal, several coating techniques have been attempted, some well-established, such as enameling, 10 spray, 11 electrophoretic deposition, 12,13 pulsed laser ablation, 14,15 radio frequency magnetron sputtering (RFMS), 16−18 and sol−gel, 19 and other novel approaches, including matrix assisted pulsed laser evaporation, 20 laser cladding, 21 high velocity suspension flame spraying, 22 and sponge replication. 23 There is also a growing interest toward the fabrication of amorphous 24,25 and crystalline 26,27 nano-or submicrometer sized organic or inorganic objects. The plethora of reported shapes includes tubes, fibers, wires, whiskers, grasses, belts, domes, pillars, cones, spheres, sheets, needles, or cones.…”

The fabrication methods of low dimensional objects can be divided according to the condensation state of the deposition environment in (i) gas phase reaction processes [e.g., chemical vapor deposition (CVD), ,, microwave plasma evaporation, and ultrahigh vacuum evaporation] and (ii) solution reaction processes (e.g., electrodeposition, ,, dip coating, and electrospinning − ).…”

Electrospun nickel oxide nanofibers: Microstructure and surface evolution

“…These include laser spinning [23], chemical precipitation [24], electrodeposition [25] and pulsed-laser evaporation [26]. In this work, we demonstrate the synthesis of NiO NFs with controlled crystallinity and crystallite size via 'electrospinning' which is an economic and industrially scalable technique for producing NFs in a continuous manner [27].…”
