作者展示了一种空芯光子晶体光纤 (HCPCF) 表面增强拉曼探针，该探针由 HPCCF 组成，气孔内表面涂有金纳米颗粒，作为表面增强拉曼散射 (SERS) 的基底。实验结果表明，HCPCF 内的光限制以及 HPCCF 气孔内纳米颗粒/分析物的涂层为光与 SERS 颗粒相互作用提供了大面积。 HPCCF 的优化设计进一步提高了探头灵敏度。
The authors demonstrate a hollow core photonic crystal fiber (HCPCF) surface-enhanced Raman probe consisting of a HCPCF with Au nanoparticles coated on the inner surface of the air holes serving as the substrate of surface-enhanced Raman scattering (SERS). The experimental results indicate that the confinement of light inside the HCPCF and the coating of nanoparticles/analyte inside the air holes of the HCPCF offer a large area for the light to interact with the SERS particles. An optimized design of the HCPCF is provided to further improve the probe sensitivity.
