Synthesis of nickel nanoparticles by pulse laser ablation method using Nd:YAG laser

Abstract

Nickel nanoparticles have interesting future prospect in various fields such as sensors, catalysts, and medical applications. The synthesis of nickel nanoparticles (NiNPs) using the pulse laser ablation method has been successfully performed by using low laser energy Neodymium Yttrium Aluminum Garnet (Nd:YAG). A high-purity nickel plate was immersed in 10 ml deionized water in a petri dish and a pulsed Nd:YAG laser (1064 nm, 30 mJ, 15 Hz) was then irradiated on the nickel surface for 20 minutes. Light grey color of colloidal NiNPs were successfully synthesized. The morphology of NiNPs shows that the spherical shape of NiNPs was produced with an average diameter of 25 nm and standard deviation of 3 nm. The surface plasma resonance was around 290 nm.
