More Information
Summary:An infrared sensor (3) and an infrared gas detector (100), the infrared sensor (3) includes electrodes (31, 34, 35), a substrate, an isolation layer (33), and a graphene film (36), wherein said graphene film (36) has a periodical nanostructure (361). The infrared sensor (3) enhances the absorption of infrared light, and is capable of only absorbing specific infrared wavelengths, thus improving the selective performance of the detector (100).
