Effect of Pd Ions on the Generation of Ag and Au Heterogeneous Nanoparticles Using Laser Ablation in Liquid

Heterogeneous Ag/Au nanoparticles combined with Pd ions were generated by irradiating metal targets in a solution nanosecond and femtosecond lasers. AgPd AuPd laser fragmentation bonded. We numerically analyzed the hot spots electromagnetic field enhancement of different sizes separated various distances. differing diameter showed characteristics compared to typical core-shell heterogeneous nanoparticles. played an important role generation liquid via ablation. The produced both pure uniform size. relatively non-uniform size, which developed into spherical (small) size presence ions. These could optimize applications such as photothermal therapy catalysis.
