Method of producing single-crystal spherical metal sodium nanoparticles

Abstract

The present invention is related to a method of producing metal sodium nanoparticles which are single crystals and spherical, and have an average particle diameter of 1 nm to 300 nm. The single-crystal spherical metal sodium nanoparticles obtained by the production method of the present invention can generate fluorescence when excited by an ultraviolet light. The single-crystal spherical metal sodium nanoparticles do not have the toxicity of compound semiconductors formed from cadmium, selenium, tellurium, etc., and therefore can be used as a reducing agent for various origin substance. Furthermore, because the single-crystal spherical metal sodium nanoparticles are spherical, they can be used as a negative electrode for a sodium battery.
