Graphene oxide induced multi-layered six-petal flower-shaped rare earth Tb³⁺ hybrid luminescent material: synthesis, characterization, luminescence and fluorescence anti-counterfeiting properties

Abstract

The graphene oxide/rare earth Tb³⁺ complex hybrid, GO-L-Tb, luminescent micron crystals with special multi-layered six-petal flower shape were facilely obtained by treatment of the L-Tb with GO in DMF solution using solvothermal method.
