Abstract
The disclosure relates to systems and methods for photonic sintering of conductive ink compositions with metal nanoparticles. Specifically, the disclosure relates to methods and systems for sintering ink compositions with metal nanoparticles using an illumination source comprising an array of pulsed light emitting diodes (LEDs).
Claims17
A method of sintering metal particle comprising
- a. coating a substrate with a pattern of a composition comprising metal nanoparticles having a predetermined thickness;
- and
- b. exposing the coated pattern of metal nanoparticle composition to an array of pulsed light emitting diodes (LEDs) at a predetermined substrate velocity in a given direction,
- wherein the LEDs are substantially monochromatic, emitting light at a wavelength corresponding to the metal nanoparticles' average size-dependent (D2,1) surface plasmon resonance (SPR) peak wavelength.
