제목 High Density Accordion-like Plasmonic Silver Nanostructure Array with Multiple Electromagnetic Responses
초록 We realized 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 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 nanodomains with the sizes of ~15 nm were alternatively stacked along the nanorod direction. After the AAO template was removed, a 5 nm thick layer of silver was thermally deposited on only PS nanodomains. Due to the multiple resonances exhibited in the visible and NIR regimes, the array could be used for multi-analyte detection.
