摘要： 用真空蒸镀银岛膜和银溶胶自组装膜两种方法对光纤探针进行表面增强拉曼(SERS)活性修饰,构造了圆锥型SERS活性光纤光谱微探针.选取几个有代表性的分子作为检测样品,得到了低浓度样品的SERS光谱,对样品BVPP的检测下限达到10-9mol/L.比较两种修饰光纤探针的检测结果可知,银溶胶自组装膜修饰更有优势.

Abstract: Surface-enhanced Raman scattering(SERS)-active optic fiber probe was fabricated with single optic fiber which modified the surface of the coned-shape fiber tip by two methods, vacuum deposited silver island and self-assemblied silver colloid. The fiber was used for both transporting the exciting laser radiation and collecting Raman scattering from the molecules absorbed onto the SERS-active substrates. Several molecules were selected to be analyzed and the molar detection limit reached 10-9 mol/L. The SERS-active optic fiber probes were used for on line or in situ detection.

Key words: Surface-enhanced Raman scattering(SERS), Optic fiber probe, Self-assembled film, Detection
