Due to the synergistic effect of enhanced nonlinear scattering, two-photon absorption, and efficient energy transfer between NaYF4: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.||URI:||https://hdl.handle.net/10356/96677
