Silver Accordion Plasmonic Nanostructure Showing Multiple Electromagnetic Responses |
| 초록 |
We realized a high-density array of accordion-shaped plasmonic silver nanorods in a large area (~ cm2) exhibiting multiple electromagnetic responses in near-infrared (NIR) and visible wavelengths. The silver accordion array was fabricated by confining lamellar-forming polystyrene-block-poly (methyl methacrylate) copolymer (PS-b-PMMA) inside cylindrical pores of aluminum oxide (AAO) template grafted by thin neutral brush layers. PS and PMMA lamellar microdomains with size of ~ 15 nm are alternatively stacked vertically along the cylindrical axis. After AAO template was removed, 5nm thick silver was thermally deposited selectively only on PS microdomains. This proposed fabrication approach demonstrated a high-density array of accordion rods with multiple resonances that could be further employed for multi-analytes detection and suggests potential employment of block copolymer self-assembly for the realization of a large-scale metamaterial with sophisticated architecture. |
