| Abstract Scope |
Recent work has demonstrated the potential for extraction of near field thermal emission of functional nanomaterials and the application for passive sensing at extreme temperatures through integration with optical fibers. This presentation will overview the fundamental operation principles of thermal emission based passive sensing devices for extreme temperatures and will present examples of functional material systems that have been investigated to date including: (1) Sn-doped In2O3, (2) La-doped SrTiO3, and (3) Au-nanorod integrated anodized aluminum oxide. Computational calculations of near-field thermal emission will be presented and the results will be compared with experimentally derived results of thermal emission for both silica and sapphire based fiber sensing platforms. Preliminary sensing results for both temperature and gas phase chemistry will also be presented, as well as a discussion of future opportunities with this technology platform. |
