PLASMONIC LIGHT ABSORBER, PLASMONIC PHOTOCATALYTIC SUBSTRATE INCLUDING SAME, AND METHOD OF MANUFACTURING SAME

摘要

The present invention relates to a plasmonic light absorber, a plasmonic photocatalytic substrate including same, and a method of manufacturing same and, more particularly, to a plasmonic light absorber characterized by comprising: a substrate; nano rods formed on the substrate and leaning in irregular directions; and a metal-containing thin film formed on the surfaces of the nano rods and the substrate, to a plasmonic photocatalytic substrate including same, and to a method of manufacturing same, wherein the nano rods, on which the metal-containing thin film is formed, form nano gaps of various sizes, for inducing surface plasmon resonance, together with adjacent nano rods. Thus, there is the effect of providing: a plasmonic light absorber capable of being manufactured to have a wide surface area and of absorbing light in a wide wavelength range at high efficiency, and a plasmonic catalytic substrate including same.
