Abstract

Plasmonics devices are usually not suitable for gas spectroscopy due to the limited enhancement length for absorption. Here, we demonstrate a plasmonic nanopatch array coated with metal-organic framework (MOF) for surface enhanced infrared absorption to detect carbon dioxide. The highest enhancement factor we achieved is over 1100 times.
