摘要

PROBLEM TO BE SOLVED: To solve such problems relating to a request for inexpensively obtaining a composite metal nanoparticle colloid with high purity and high concentration, that a composite metal nanoparticle colloid by a chemical production process is difficult to obtain because of limitation in combinations of metals due to restriction of chemical reactions, problems in compounds and by-products, complicated production processes, difficulty in the production and high production costs, and that a composite metal nanoparticle colloid cannot be obtained by a physical production process.SOLUTION: The above problem is solved by improving a physical production process and by using a method for capturing a metal vaporized in vacuum by use of a surfactant only.SELECTED DRAWING: Figure 1
