Abstract:Nanostructure surface composed of tetrapod-like structure with the period of about 2 μm has been made by simple nanoprinted method, the collodion was poured directly on the surface of the template and tore off after it became solidification, and then a layer of gold was sputtered on the collodion surface. The electric field distributions of the tetrapod-like structure with different size and period have been simulated using finite element method. Surface-enhanced Raman spectra mapping image gotten from the substrates illustrated the uniform enhancement property of it. The diluted aqueous solution of Rhodamine 6G (50 nM) was used to test the enhanced property of substrates for trace detection and good quality spectra has been gotten. The spectra of melamine with the concentration of 1 mg/L (7.9 μM) on the substrates were gotten to show the enhanced ability for molecule with small Raman scattering cross section.
