赤外線吸収体および赤外線吸収体を備えるガスセンサ
Document Type and Number:
Japanese Patent JP7240666
Kind Code:
B2
Abstract:
To provide an infrared absorber which can be easily manufactured by a lithography technique and can absorb or radiate infrared rays, and a gas sensor having the infrared absorber.SOLUTION: The infrared absorber according to the present invention is an infrared absorber 1 capable of absorbing or radiating infrared rays. The infrared absorber 1 includes: a first metal layer 2 located on a surface side, which is irradiated with infrared rays or irradiates infrared rays; a second metal layer 3, which reflects infrared rays between the first metal layer 2 and the second metal layer 3; and dielectric layers 4 and 5 between the first metal layer 2 and the second metal layer 3, the dielectric layers transmitting infrared rays, the dielectric layers 4 and 5 having a laminated structure of the first dielectric layer 4 on the first metal layer 2 side with a first index of refraction and the second dielectric layer 5 on the second metal layer 3 side with a second index of refraction smaller than the first index of refraction.SELECTED DRAWING: Figure 2
