Schematic representation of Print-Light-Synthesis for electrode production. “Print” (left panel): Inkjet printing of a well-defined, confined ultra-thin reaction volume containing one or more dissolved metal precursor salts with highly controllable loading (e.g., few μg/cm²). Inkjet printing enables the fabrication of micrometrically resolved patterns. “Light” (central panel): Short irradiation of the as-deposited liquid precursor film converting the metal precursor into the desired material; the vicinity of the precursor to the substrate surface favors the deposition on the substrate rather than the synthesis of particles in the solution. “Synthesis”: The result of the process is a film of metal or mixed metal nanoparticles or nanostructures (depending on the process parameters), while all other ink components have been degraded and/or evaporated.
