Abstract: A metal nanoparticle ink composition comprises an ink vehicle and a plurality of metal nanoparticles dispersed in the ink vehicle. The metal nanoparticles including both a first organic stabilizing group and a second organic stabilizing group attached thereto, the first organic stabilizing group being different from the second organic stabilizing group, the first organic stabilizing group being selected from the group consisting of decylamine, undecylamine, dodecylamine, tridecylamine, tetradecylamine and mixtures thereof, and the second organic stabilizing group being selected from group consisting of butylamine, pentylamine, hexylamine, heptylamine, octylamine, nonylamine, decylamine and mixtures thereof.

Abstract: A nanoparticle composition comprising a plurality of stabilized metal-containing nanoparticles comprising silver and/or a silver alloy composite. The stabilized metal-containing nanoparticles are prepared by a method comprising reacting a silver compound with a reducing agent comprising a hydrazine compound by incrementally adding the silver compound to a first mixture comprising the reducing agent, a stabilizer and a solvent. The stabilizer comprises a mixture of a first organoamine and a second organoamine, an alkyl moiety of the first organoamine having a longer carbon chain length than the alkyl moiety of the second organoamine. The first organoamine is selected from the group consisting of decylamine, undecylamine, dodecylamine, tridecylamine, tetradecylamine and mixtures thereof. The second organoamine is selected from group consisting of butylamine, pentylamine, hexylamine, heptylamine, octylamine, nonylamine, decylamine and mixtures thereof.
