Abstract

We report an new approach of integrating photonic crystal fiber (PCF) SERS sensors to a Raman spectrometer for high sensitivity to the explosive 2,4,6-trinitrotoluene (TNT). The PCF SERS probe can be fabricated by using gold nanoparticles immobilized on the inner surface of air channels in a PCF through polymer-mediated self-assembly. To study the response of above fabricated substrates to the TNT vapor, the PCF SERS probe integrated with a Raman spectrometer was proposed and demonstrated in this study. The TNT-induced SERS signals are measured and the sensing capability of the proposed sensors is investigated experimentally.
