Synthesis of colloidal zinc nanoparticles by pulse laser ablation technique using fundamental Nd:YAG laser 1064 nm

Abstract

The synthesis of high-purity Zinc nanoparticle (ZnNPs) using the pulse laser ablation method has been successfully performed. In this study, Low-power neodymium-doped yttrium aluminum garnet (Nd:YAG) laser was used as an energy source. Pulse laser beam (1064 nm, 7ns, 10 Hz) was focused on a high-purity (99.95%) zinc plate surface, which was immersed in 10 ml of aquadest. Light brownish color of colloidal ZnNPs was successfully produced. The SEM image of ZnNPS shows that the produced nanoparticle had a spherical shape. The average diameter of ZnNPs was 35 nm with a standard deviation of 8.7 nm, and the surface plasmon resonance is located approximately at 300 nm.
