Copper-containing nanoparticles with excellent oxidation resistance is provided. The present invention relates to a method for manufacturing copper-containing nanoparticles including obtaining copper-containing nanoparticles that contain an organic component by heat treating an organic copper compound at a temperature equal to or higher than a decomposition initiation temperature of the compound and lower than a complete decomposition temperature of the compound in a non-oxidative atmosphere in the presence of an organic material containing a 1,2-alkanediol having 5 or more carbon atoms and/or a derivative thereof.
A method for manufacturing copper-containing nanoparticles, comprising a step of obtaining nanoparticles containing an organic component, copper and cuprous oxide by heat treating an organic copper compound at a temperature equal to or higher than a decomposition initiation temperature of the compound and lower than a complete decomposition temperature of the compound in a non-oxidative atmosphere in the presence of an organic material containing (1) a tertiary amine compound and (2) a 1,2-alkanediol and/or a derivative thereof, wherein the number of carbon atoms in the 1,2-alkanediol or a derivative thereof is 8 to 30.
Copper-containing, nanoparticles comprising an organic component, Cu and Cu2O in each particle, wherein an intensity ratio of Cu2O in an X-ray diffraction pattern is 50% or less given 100% as the total of intensities of Cu and Cu2O, and wherein the organic component contains at least one of a 1,2-alkanediol with 5 or more carbon atoms, a derivative thereof and a component derived from these.
