Mechanism Studies on the Superior Optical Limiting Observed in Graphene Oxide Covalently Functionalized with Upconversion NaYF4:Yb3+/Er3+ Nanoparticles. Small, 8(14), 2163-2168. | Series/Report no.: | Small | Abstract: | 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 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 http://hdl.handle.net/10220/10386 |
