“…Moreover, the weak formation of a byproduct on the surface of the tungsten target was observed, which may obviously affect the laser−target interaction. According to Bottjer et al, Ag(I) reduction and WNO 3 formation may also take place on the tungsten target surface. Therefore, we expect silver NPs smaller than those obtained with Si and Ge targets, given the higher temperature reached at the W surface enhancing the reaction kinetics, as shown in Figure a−d.…”

Here we describe a simple, powerful technique based on the laser ablation of a target immersed in a water solution of a metal salt. With this method, nanoparticles of different metals and alloys can be processed very quickly. Both the target and the salt solution can be chosen to produce metal nanoparticles of different sizes, surface-oxidized nanoparticles (silica-silver, for example), or even more complex structures to be defined by the researcher on one or more steps because the technique combines the advantages of both physical and chemical methods. We have applied this technique to the fabrication of inert silica-metal (silver, gold, and silver-gold) nanoparticles with a strong surface plasmon resonance all together in a single step. The advantage of the simultaneous production of silica during laser ablation is the stabilization of the metal nanoparticle colloid but also the possibility to reduce the toxicity of these nanoparticles.
