Abstract

A metal microparticle composite is provided, which includes a film-shaped matrix resin and metal microparticles immobilized in the matrix resin. The metal microparticles are obtained by reducing metal ions or metal salts, and the particle diameters of at least 90% of all the metal microparticles are in the range of 10 nm to 80 nm. The metal microparticles that are dispersed in a plane direction parallel to the matrix resin surface in a range of depth within 150 nm from the matrix resin surface to form a metal microparticle layer, and only one metal microparticle having the diameter described is present in the direction of depth in the metal microparticles layer. The spacing between adjacent metal microparticles is greater than and equal to the particle diameter of the larger one of the adjacent metal microparticles.

Description

technical field

[0001] The present invention relates to metal microparticle composites that can be used in various devices utilizing, for example, surface plasmon resonance. Background technique

[0002] Local Surface Plasmon Resonance (LSPR) is a phenomenon in which electrons in metal particles or metal microstructures with a size of several nm to 100 nm interact with light of a specific wavelength to resonate. Localized surface plasmon resonance has long been used in colored glass that exhibits vivid colors by mixing metal particles inside the glass. In recent years, research has been conducted on applications such as development of high-output light-emitting lasers utilizing the effect of enhancing light intensity, biosensors utilizing the property of changing resonance states upon molecular bonding, and the like.

[0003] In order to apply such localized surface plasmon resonance of metal fine particles to sensors and the like, it is necessary to stably immobilize the m...
