title: Formation of flower-like Ag colloids using pulsed proton beam.
abstract: A new solution phase method is presented for the synthesis of "flower-like" silver nanomaterials using a pulsed proton beam irradiation process at room temperature. It was observed that the morphology of the prepared silver crystals was easily controlled by varying the number of exposures to the pulsed proton beam. The synthesized flower-like silver nanocrystals exhibited excellent surface enhanced Raman scattering (SERS) signals, which were attributed to the rough microstructures on the surface of the synthesized Ag crystals.
