Abstract:

We study the fabrication and application of the fractal silver nanostructure using an electrochemical process. Scanning electron microscope and high resolution transmission electron microscope images show the morphology of silver nanostructure can be well controlled via the various reaction times. The surface enhanced Raman scattering of 10 μM aqueous Rhodamine 6G (R6G) solutions conducted in as-fabricated silver nanostructure achieved an enhancement factor approximately 105 at room temperature. Meanwhile, an approximately 104 enhancement factor of SERS signal can be kept under 200 °C in present study. This study can help us to integrate the nano-metals and nano-particles for advanced nano devices.
