| Abstract | The growth of Au nanoparticles by laser ablation processes has been systematically investigated. The morphology of Au metal nanoparticles was characterized with respect to laser wavelength, pulse duration, pulse energy, and surfactant concentrations in order to understand the nanoparticle formation process during laser ablation. Three different laser wavelengths, including a nanosecond excimer laser operating at 248 nm, femto-second Ti-Sapphire laser operating at 776 nm and nano-second diode-pumpeg Nd:YAG laser operating at its second harmonic wavelength of 532 nm were used for Au nanoparticle fabrication in surfectant-free and surfectant-containing aqueous solutions. Field emission SEM, XRD and UV-visible absorbtion spectrum were used for the characterization of Au nanoparticles. The parameters controlling the morphology of Au nanoparticles during laser ablation in surfectant-free and surfectant-containing aqueous media are discussed. It was found that nanosecond Nd:YAG and KrF excimer lasers are the better choice than femtosecond Ti:Sapphire for the fabrication of Au nanoparticles with smaller particle size and narrower particle size distributions. |
