摘要

Superior optical limiting (OL) characteristics and mechanisms are explored in a novel nanocomposite made from graphene oxide (GO) and NaYF ₄:Yb³⁺/Er³⁺ nanoparticles via covalent chemical bonding. Due to the synergistic effect of enhanced nonlinear scattering, two-photon absorption, and efficient energy transfer between NaYF ₄:Yb³⁺/Er³⁺ nanoparticles and GO, the nanocomposite displays dramatically improved OL effects compared to either GO or NaYF₄:Yb³⁺/Er³⁺ nanoparticles, making it a very promising material for practical OL devices.
