Abstract
The present invention has an object of providing a single-stage production method that enables the production of ultra fine metal nanoparticles and ordered alloy nanoparticles within solution. The production method includes irradiating a solution of a salt or complex of a metal element, thereby decomposing and/or reducing the salt or complex within the solution and generating metal nanoparticles having an average particle size within a range from 0.3 to 100 nm within the solution.
