Embodiment Construction

[0014] figure 1 (a) is a perspective view schematically showing the thermo-optic conversion element A of the first embodiment having a plurality of cavities formed by concavo-convex patterns on the surface of the substrate, figure 1 (b) is schematically shown figure 1 (a) is a graph showing the radiation characteristics of the thermo-optic conversion element A.

[0015] Such as figure 1 As shown in (a), the thermo-optic conversion element A of the first embodiment has, for example, a structure in which concavo-convex portions having concave portions 3 a and convex portions 3 b are arranged at a pitch P of 2 μm or less on the surface layer portion 1 a of the base body 1 constituting a hexahedron. Pattern 3. That is, in the thermo-optic conversion element A, the concave-convex pattern 3 is formed by forming concave portions 3 a at predetermined intervals on the upper surface side of the substrate 1 . In addition, in the substrate 1, the surface layer portion 1a including at ...

Abstract

A thermal-optical conversion element has a substrate (1) formed from metal, ceramic, or a composite combining these. The substrate (1) has a plurality of concave and convex patterns that comprise a concave portion (3a) and a convex portion (3b) and that are disposed to have a pitch of no more than 2 [mu]m, and the substrate (1) has a surface layer (1a) that is porous. The substrate (1) has a plurality of cavities. The substrate (1) is a three-layered structure of a first metal layer (1A), a dielectric layer (1B), and a second metal layer (1C), wherein the second metal layer (1C) forms a convexportion (3b), and between second metal layers (1C) is a concave portion. A heat absorbing member (7) is provided on a face that is on the side opposite to the face having the concave and convex pattern (3) of the substrate (1).

Description

technical field [0001] The present disclosure relates to thermo-optic conversion elements. Background technique [0002] After the industrial revolution that occurred in the 18th century, various industries began to develop. On Earth, the consumption of fossil fuels is increasing. Therefore, the exhausted carbon dioxide gas is trapped in the sky and acts as a greenhouse effect gas. On the ground, the cooling effect on the ground gradually decreases due to the buildings made of concrete, asphalt roads. Therefore, the use of refrigeration equipment is gradually increasing. In addition, infrared rays emitted from concrete and asphalt are absorbed by the atmosphere and clouds, so energy cannot be released outside the Earth's circle. In this way, a vicious cycle occurs in which an increase in the usage of fossil fuels leads to a further increase in greenhouse gases (see, for example, Non-Patent Document 1). Currently, there is a situation where no key technology has been fou...
