Abstract:
1. A method for fabricating liquid ink comprising: forming non-oxide metal nanoparticles containing elements from group IB; forming non-oxide metal nanoparticles from group IIIA; and adding one or more liquid metals containing one or more elements of group IIIA; intermixing the non-oxide nanoparticles from groups IB and IIIA and one or more liquid metals from group IIIA, wherein the particles are in a desired particle size range of between about 0.1 nm and about 500 nm in diameter, wherein, for each element metal, a majority of the mass of the metal nanoparticles range in size from no more than about 40% above or below an average particle size, or, if the average particle size is less than about 5 nanometers, from no more than about 2 nanometers above or below the average particle size; and mixing the particles to form a liquid that serves as an ink.
