Abstract
Fe@Au is a type of nanoparticle that contains magnetic Fe NPs core with a fine layer of Au NPs synthesized using the Pulsed Laser Ablation in Liquid (PLAL) Method. These Fe@Au NPs characterized by Atomic Force Microscope (AFM), Field Emission Scanning Electron Microscopy (FESEM), and UV-Visible Spectrophotometer. The result was obtained at different laser fluences (1.9, 2.2, and 2.5) J/cm2 with fixed pulse duration 5 ns, wavelength 532nm and number of pulse equal 100 pulsed. The obtained mean size of Fe@Au NPs at laser fluence (1.9, 2.2, and 2.5) J/cm2 was (63.65, 32.47 and 31.18) nm respectively. UV-Visible Spectrophotometer carves was showed a redshift toward longer wavelength by increasing particle size. Obtained results exhibited that the laser fluence plays a key role in the size, and dispersity of Fe@Au NPs.
