A galvanically replaced composite nanocrystal based metamaterials for plasmonic applications – Metamaterials 2018

We demonstrate the simple fabrication way of the tunable, thermally and chemically stable plasmonic metamaterials using nanoimprinting and galvanic replacement process. By galvanic replacement process, the Ag-Pt (or Ag-Au, Ag-Pd) composite metamaterials were fabricated and the optical plasmonic resonances were controlled for various applications.
