Dynamic switching of plasmonic monolayers built of gold nanoparticles (AuNPs) is achieved using nano-coatings of poly(isopropyl acrylamide) (PNIPAM). The distance between AuNPs can be dynamically tuned through the repeatable expansion and contraction of the PNIPAM shells at different temperatures, which results in rapid switching of the optical properties of the AuNP monolayer.
通过聚异丙基丙烯酰胺(PNIPAM)的纳米涂层实现了由金纳米粒子(AuNPs)构建的等离子体单分子层的动态切换。通过在不同温度下 PNIPAM 壳的重复膨胀和收缩,可以动态调整 AuNPs 之间的距离,从而导致 AuNP 单分子层的光学性质的快速切换。
