利用一种简单、高效、低成本的水热方法，在多模光纤的锥形尖端制备了基于银纳米片的表面增强拉曼散射(SERS)光纤探头。场发射扫描电子显微镜和透射电子显微镜表明，所得到的光纤探头由厚度约为40 nm、平均长度为300 nm的纳米片组成。以4-氨基硫酚为探针分子，对锥形光纤探头的SERS活性进行了优化，得到了较好的结果。
We report on surface-enhanced Raman scattering (SERS) fiber probe based on silver nanoplates which are fabricated on the tapered tip of the multimode fiber, by a simple, effective and low-cost hydrothermal method. The field-emission scanning electron microscopy and the transmission electron microscopy show that the obtained fiber probe is composed of nanoplates with the thickness of about 40 nm and an average length of 300 nm. The SERS activity of the tapered fiber probe with an optimal cone angle has demonstrated excellent results using the probing molecule of 4-aminothiophenol.
