RESEARCH on OPTICAL FIBER SENSOR BASED on NANOPARTICLES-MODIFIED

摘要：

This article makes a study on optical fiber sensor with metal nanostructure based on the properties of optical fiber sensing technology and the optical performances of metal nanoparticles. Moreover, star-sha ped gold nanoparticles which mean diameter is from 60 to 80 nm were obtained by the Seed-mediated growth method .Then these nanoparticles were used as the sensitive part of the optical fiber sensor and were modified to the tapered fiber surface as a surface Raman enhanced substrate. Finally, transmission spectrum and Raman spectra were carried out in different concentration alcohol solution. The experiments show that the extinction, spectra of gold nanoparticles is very sensitive to the dielectric properties of the surrounding medium and the nanoparticles fiber-taper-excited SERS (Surfaceenhanced Raman scattering) substrates exhibit a significant enhancement of the Raman spectra.
