Title:
積層型ふく射光源
Document Type and Number:
Japanese Patent JP6994274
Kind Code:
B2
Abstract:
Provided is a radiation light source that enables adjustment of infrared radiation to a significantly narrow band. A plasmonic reflector layer consisting of a plasmonic material, a resonator layer consisting of an insulator, and a partially reflecting layer are alternately laminated in this order to form a multi-layered radiation light source, wherein the partially reflecting layer are selected from any one of a free interface, an ultrathin-film metallic layer, and a distributed reflector layer having a structure in which layers having different refractive indexes are alternately laminated. When a material with high-temperature resistance such as SiC is used in the outermost layer of the distributed reflector layer, the multi-layered radiation light source can operate at high temperatures of 550° C. and higher.
