A plasmonic structure using gold nanorods (GNRs) on the surface of a tapered fiber was developed. The structure was used to study the Raman spectra of Rhodamine 6G (R6G) and zinc oxide (ZnO) adsorbed on the tapered optical fiber covered with the GNRs, respectively. The tapered optical fiber was manufactured by a dynamic etching process. The tapered fiber had a tip diameter in the nanometer range. The optical tweezing phenomenon was used to develop the plasmonic structure along the length of the tapered fiber surface. The density of GNRs varied as the diameter of the fiber in the tapered region changed. Raman spectra for R6G and ZnO were recorded and analyzed at different fiber locations with and without GNRs. We could obtain the SERS spectrum of a R6G solution of concentration 10−7 M using the developed substrate.

锥形光纤上的等离子体结构,用作表面增强拉曼光谱基底
开发了在锥形纤维表面使用金纳米棒 (GNR) 的等离子体结构。该结构用于研究分别吸附在覆盖有 GNR 的锥形光纤上的罗丹明 6G (R6G) 和氧化锌 (ZnO) 的拉曼光谱。锥形光纤是通过动态蚀刻工艺制造的。锥形光纤的尖端直径在纳米范围内。光学镊子现象用于沿锥形光纤表面的长度发展等离子体结构。GNR 的密度随着锥形区域中纤维直径的变化而变化。R6G 和 ZnO 的拉曼光谱在有和没有 GNR 的不同光纤位置记录和分析。我们可以获得浓度为 10 -7的 R6G 溶液的 SERS 光谱 M 使用开发的基板。
