Synthesis of Ni Nanoparticles by Pulsed Laser Ablation Method in Liquid Phase

Laser ablation in liquids has been intensively studied in recent years, due to present numerous potentials in laser material micro-processing, including nanomaterials and nanostructures synthesize. Compared to others, typically chemical methods, pulsed laser ablation (PLA) in liquid is a simple and “green” technical method that normally operates in water or organic liquids under ambient conditions. Here, pure Ni nanostrutures were synthesized using PLA method in 30 mL of acetone. A simple fiber pulsed laser setup has been not only employed to reduce the micron Ni particles to nano-sized by the PLA method, but also with no-induced oxidation at room temperature and free additive in liquid. The particle size, spectral analysis and morphology of the products were characterized by UV-vis spectrometry, energy-dispersive X-ray spectroscopy (EDX) and transmission electron microscopy (TEM). The TEM image indicates spherical shapes with a narrow size distribution, compared with other methods, with ∼10 nm in diameter respectively.
