Superior optical limiting (OL) characteristics and mechanisms are explored in a novel nanocomposite made from graphene oxide (GO) and NaYF4:Yb3+/Er3+ nanoparticles via covalent chemical bonding. Due to the synergistic effect of enhanced nonlinear scattering, two-photon absorption, and efficient ener...
