Abstract
Ligand-capped scattering nanoparticles, curable ink compositions containing the ligand-capped scattering nanoparticles, and methods of forming films from the ink compositions are provided. Also provided are cured films formed by curing the ink compositions and photonic devices incorporating the films. The ligands bound to the inorganic scattering nanoparticles include a head group and a tail group. The head group includes a polyamine chain and binds the ligands to the nanoparticle surface. The tail group includes a polyalkylene oxide chain.
