Abstract

Remote surface enhanced Raman spectroscopy (SERS) imaging of an adsorbed monolayer was demonstrated through a nanostructured array of conical tips inscribed onto the distal face of a 30 cm optical fiber bundle. Despite intense Raman signal from the germanium oxide doped fibers, the Raman signal of an adsorbed monolayer of a reference compound (benzene thiol) was detected in the fingerprint region. This opens up the possibility of local remote imaging through an optical fiber that embeds a SERS active platform.

摘要

通过刻蚀在30厘米光纤束远端表面的纳米结构锥形尖端阵列，实现了对吸附单层的远程表面增强拉曼光谱（SERS）成像。尽管掺杂氧化锗的光纤产生了强烈的拉曼信号，但仍在指纹区检测到了参考化合物（苯硫醇）吸附单层的拉曼信号。这为通过嵌入SERS活性平台的光纤进行局部远程成像开辟了可能性。
