摘要： A method for manufacturing metal nanorods includes: a step of adding a reducing agent to a metallic salt solution; a step of radiating light into the metallic salt solution containing the reducing agent; and a step of leaving the light-radiated metallic salt solution containing the reducing agent stationary in a dark place so as to grow metal nanorods. Metal nanorods can be also grown by forming a mixed solution by fractionating the above light-radiated metallic salt solution and mixing the fractionated metallic salt solution into a non-radiated metallic salt solution containing the reducing agent, or mixing a non-radiated metallic salt solution and the reducing agent into the above light-radiated metallic salt solution; and leaving the mixed solution stationary in a dark place so as to grow metal nanorods.

摘要： Metal microparticles that exhibit selective wavelength absorption capability over a wavelength region from visible light to near infrared light, having sharp light absorption characteristics and that have less influence on ambient wavelengths, realizing color tone of high saturation. There are provided metal microparticles characterized in that the aspect ratio thereof is in the range of 1.1 to 8.0, the maximum absorption wavelength of plasmon absorption in the range of 400 to 1,200 nm and the absorptivity at maximum absorption wavelength peak position in the range of 6,000 to 20,000 L/mol·cm (measurement concentration: 1.6×10-4 mol/L and solvent: water).
