Abstract:

A composition for the fabrication of reflective features using a direct-write tool is disclosed. The composition comprises metal nanoparticles having an average particle size less than 300 nm and which carry thereon a polymer for substantially preventing agglomeration of the nanoparticles, wherein the nanoparticles exhibit a metal-polymer weight ratio of 100:1 to 10:1. The composition further includes a vehicle for forming a dispersion with the metal nanoparticles. A number of electronic devices comprising a reflective layer formed from the composition are also disclosed. One example case provides an electronic device having a reflective electrode. The reflective electrode comprises a percolation network of the metal nanoparticles embedded in a matrix of the polymer and having an average particle size of less than 300 nm, wherein the reflective electrode is reflective in the visible light range and does not diffract incident light.
