Synthesis and spectral characteristics of La2MoO6：Ln3＋ （Ln=Eu, Sm, Dy, Pr, Tb） polycrystals
The novel phosphors of La2MoO6 activated with the trivalent rare earth Ln3＋ （Ln=Eu, Sm, Dy, Pr, Tb） ions were synthesized by solid state reactions at high temperature in air atmosphere, and their phase impurities and luminescent properties were studied. The photolu- minescence （PL） excitation and em...

| description | The novel phosphors of La2MoO6 activated with the trivalent rare earth Ln3＋ （Ln=Eu, Sm, Dy, Pr, Tb） ions were synthesized by solid state reactions at high temperature in air atmosphere, and their phase impurities and luminescent properties were studied. The photolu- minescence （PL） excitation and emission spectra, and decay curves were employed to study their luminescence properties. The lifetimes of the characteristic emissions from Ln3＋ ions were in the order of millisecond except Pr3＋ ions. （LaEu1-x）2MoO6 was a promising phosphor for practical application and the optimum concentration was x=0.075. The concentration quenching mechanism of Eu3＋ was also discussed by theoretical fitting using Burshtein model. |
