Preparation and properties of noble metal core/shell nanostructures prepared by excimer laser ablation in liquid solutions
Source abstract
Abstract
A new method of synthesis Ag/Au core/shell nanostructure with ultraviolet (UV) excimer laser was studied. It was found Ag/Au core/shell nanostructures with spherical shell could be prepared by UV excimer laser which is obviously confirmed by high resolution transmission electron microscopy. The surface plasma resonance of this nanostructure can be tuned by controlling thickness of the Au shell. Simulation based on Mie theory was in agreement with the result of the experiments. Moreover, it is indicated the Ag/Au core/shell nanostructure has excellent activity in surface-enhanced Raman scattering. This Ag/Au core/shell nanostructure may be applied to high sensitive trace detection in the future.
