  • INFRARED LIGHT ABSORBENT BODY, AND GAS SENSOR PROVIDED WITH INFRARED LIGHT ABSORBENT BODY
    Publication number: 20240053261
    Abstract: The infrared absorber 1 is provided with a finely structured metal layer 2 which causes local surface plasmon resonance by absorption infrared light; a dielectric layer 3 under the finely structured metal layer, and a metal layer 4 under the dielectric layer 3. The dielectric layer 3 is stacked between the layers 2 and 4 and consists of an organic polymer material having a molecular bond whose vibration is excited by infrared absorption. Further, the gas sensor is provided with the infrared absorber as the light source and/or the photodetector.
