Arrays of triangular shaped pincushions for SERS substrates prepared by using self-organization and vapor deposition.
Silver spike arrays with triangular sharp edges were prepared by using a self-organization process based on the condensation of water droplets and the vapor deposition process. Strongly enhanced Raman scattering of rhodamine 6G on the spike arrays were shown.
