Abstract

Intense pulsed light sintering (IPL) of nanoparticles on rigid or flexible substrates enables rapid fabrication of thin films and patterns over large areas. In IPL, visible light from a high energy xenon lamp is absorbed by the nanoparticles for rapid sintering of metallic and non-metallic nanoparticles. This plasmonic optical absorption during the process for metal nanoparticles has been shown to depend on individual nanoparticle size. However, but there is little understanding of how this absorption depends on nanoparticle size distribution during IPL. This work incorporates a fully three-dimensional packing model along with an electromagnetic model of plasmonic absorption in silver nanoparticles to bridge this gap. It is shown that smaller standard deviation in a unimodal distribution and smaller size ratios in a bimodal distribution demonstrate relatively higher optical absorption in IPL.
