文摘

BaGdF₅:Ce³⁺, Ln³⁺ (Ln=Eu and Tb) nanoparticles with tunable multicolor emission and magnetic property were fabricated by a facile hydrothermal process. The citrate ions as ligand and shape modifier was introduced into the reaction system to modulate the crystal phase and shape of the products. By simply adjusting the relative concentrations of co-doped Eu³⁺/Tb³⁺ ions, the multicolor luminescence in BaGdF₅ host lattice is realized successfully. In addition, the BaGdF₅:Ce³⁺,Tb³⁺ sample shows paramagnetic property at room temperature with mass magnetic susceptibility value of 0.71脳10^鈭? emu/g Oe. The as-prepared multifunctional nanomaterials may find potential applications in displays and multiple biolabels.
