摘　　要：以普通的石英光纤为材料,用管腐蚀的方法制备出光纤探针,在管上镀一层银膜后,可构成具有表面增强特性的管状光纤探针.将拉曼光谱仪与自制的光纤探针结合起来,建立了增强型微区拉曼光谱分析系统,测量了几个具有代表性样品的拉曼光谱,实验表明该装置样品浓度检测下线为10-9mol/L.By using the single mode quartz optical fibers,several optical fiber probes were fabricated with tube etching method.Then the gained probe was treated with electroless plating silver on the surface of tubes.Combining the Raman spectroscope with a Fiber-optic probes of surface-enhanced Raman scattering,we established the site size Raman spectroscope.Based on the setup,several samples were selected to be analyzed.It shows that the molar detection limit can be reached about 10^-9 mol/L.
