Novel 3-D Nanostructures for Optical Metamaterials based on Block Copolymer Self-Assembly |
| 초록 |
We fabricated a high-density array of “accordion-like” plasmonic silver nanorods over a large area exhibiting multiple electromagnetic responses in visible and near-infrared (NIR) wavelengths. This array of “accordion-like” silver nanorods was prepared 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. Due to the multiple resonances exhibited in the visible and NIR regimes, the array could be used to realize large-scale metamaterials working at visible and NIR wavelengths. We also prepared stacked split ring resonators by utilizing “pagoda-like” metal nanostructures. They showed optical polarization difference. Finally, split ring resonators (SSR) were fabricated over a large area |
