FINE METAL PARTICLE DISPERSION COMPOSITE AND SUBSTRATE FOR GENERATING LOCALIZED SURFACE PLASMON RESONANCE

摘要

PROBLEM TO BE SOLVED: To provide a fine metal particle dispersion composite capable of preferably used for various kinds of devices using localized surface plasmon resonance, and a method for manufacturing the same.;SOLUTION: A nano composite 10 includes a matrix layer 1 and fine metal particles 3 fixed to the solid skeleton part 1a of the matrix layer 1. The solid skeleton part 1a includes an aluminum oxyhydroxide or an alumina hydrate and has a three-dimensional network structure. The average particle size of the fine metal particles 3 is 3-100 nm. The fine metal particles 3 are not contacted to each other, exist at an interval of a particle size D_L or more having a larger particle size D in adjacent fine metal particles 3, include parts exposed to the air-spaces 1b of the matrix layer 1 and exist in a state of being three-dimensionally dispersed into the matrix layer 1.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
