Bimetallic nanoparticles for conductive ink applications

摘要

A method of forming conductive features on a substrate from a solution of metal nanoparticles by providing a depositing solution and liquid depositing the depositing solution onto a substrate. The depositing solution is then heated to a temperature below about 140 °C to anneal the first and second nanoparticles and remove any reaction by-products. The depositing solution may be comprised of a mixture of first metal nanoparticles and second metal nanoparticles or a combination of first metal nanoparticles and a soluble second metal nanoparticle precursor. Furthermore, the average diameter of the first metal nanoparticles is about 50 nm to about 100 µm and the average diameter of the second metal nanoparticles is about 0.5 nm to about 20 nm.
