Abstract/OtherAbstract:
Pulsed laser ablation in liquid (PLAL) has been well established as a facile method to produce nanoparticles from bulk materials, but it is still insufficient for fabricating anisotropic and complex nanostructures, especially without the use of surfactants. Here, we demonstrate that silver (Ag) nanosheets can be produced by pulsed excimer laser ablation of bulk Ag in water via laser re-processing of the laser-produced primary clusters. We also show that by combining PLAL and drop evaporation, rice-shaped Ag-Ag(2)O particles and their assemblies can be generated on Si substrates, because the interior flow of an evaporating colloidal drop could redistribute the laser-produced primary clusters, which results in the formation of complex nanostructures. These results show that PLAL is able to fabricate novel micro-/nanostructures while keeping its merit of "clean" fabrication.
