文摘

Uniform and well-dispersed NaTb(MoO₄)₂ hierarchical nanoflowers have been fabricated via a hydrothermal method by using trisodium citrate as additive. The morphology and particle size of the NaTb(MoO₄)₂ samples can be tuned in a controlled manner by altering the pH value of the initial solution, reaction temperature, and component of solvent. The Eu³⁺-doped NaTb(MoO₄)₂ sample mainly shows the characteristic emission of Eu³⁺ corresponding to ⁵D₀–⁷F_J (J=1, 2, 3, 4) transitions due to an efficient energy transfer from MoO₄²⁻ and Tb³⁺ to Eu³⁺. The as-synthesized NaTb(MoO₄)₂:Eu³⁺ may be applied as a novel red phosphor in optoelectronic devices or advanced flat panel displays.
