Abstract
  • This dissertation focuses on extending the application scope of surface enhanced infrared absorption spectroscopy to gas sensing. The method we propose is incorporating plasmonic nanostructures with nano-composite material, metalorganic framework, which can selectively preconcentrate certain gas molecules into the nanopores. The preconcentrating property is first demonstrated by applying metal-organic framework to optical fiber based sensor. Then two different metal-organic framework integrated surface enhanced infrared absorption gas sensors fabricated on bulk substrate and nano-membrane are investigated, and the high enhancement factors demonstrated for the first time. Lastly, an on-chip spectrometer using high resolution plasmonic filter array is proposed and experimentally demonstrated for resolving CO2 absorption spectrum at 2.0 μm with 10 ~ 12 nm resolution. This filter array spectrometer is simple and low-cost, which can be potentially used for portable gas spectroscopy system.
