Abstract
We show the experimental observation of SERS inside metal nanoshells for the first time. Giant enhancement, solely due to the electromagnetic enhancement in the near field and on the order of 10(11) to 10(14), can be consistently and reproducibly achieved. The results provide new insights to the SERS effect and pave the way for a new design of nanostructures to be used as SERS-tags for Raman-based assays and imaging.
摘要
我们首次展示了在金属纳米壳内部进行表面增强拉曼散射（SERS）的实验观察结果。仅由于近场中的电磁增强，就可以始终如一地、可重复地实现高达10的11次方到10的14次方的巨大增强。这些结果为SERS效应提供了新的见解，并为设计用作基于拉曼的检测和成像的SERS标签的新型纳米结构铺平了道路。
