Abstract

Au nanoparticles (NPs) deposited on a substrate function as ring shaped colloidal shadow masks. Using e-beam evaporation of gold, nanometer sized gaps are formed as a result. The size of these gaps can be accurately tuned by controlling the thickness of the gold deposition, thereby tuning the plasmonic coupling of the NPs with the substrate. The clean cavity produced between the Au NPs and the Au film provides an excellent SERS platform for trace molecule detection.

摘要

沉积在基底上的金纳米颗粒（NPs）起到环形胶体掩膜的作用。通过金的电子束蒸发，会形成纳米尺寸的间隙。这些间隙的大小可以通过控制金沉积的厚度来精确调节，从而调节纳米颗粒与基底的等离子体耦合。在金纳米颗粒和金膜之间产生的洁净腔为痕量分子检测提供了一个出色的表面增强拉曼光谱（SERS）平台。
