Abstract
This presentation reports the use of nanostructured sapphire optical fiber (NSOF) with Au nanorods entrapped in anodized aluminum oxide (AAO) cladding for surface-enhanced Raman spectroscopy (SERS) sensing at elevated temperatures. Specifically, Au nanorods were fabricated in AAO pore channels by in-situ electroless reduction aided with Au nanoparticle catalysts. We show that the AAO pore channels endow the Au nanorods with enhanced thermal stability through geometrical confinement at up to 1000°C. The NSOF with entrapped Au nanorods was used for SERS measurements at temperatures ranging from room temperature to 800°C. The capacity of the novel fiber structure for sensing of hot gases in harsh environments was demonstrated.
