Abstract: A series of novel Li 2 Y 4 (MoO 4 ) 7 : Ln 3+ (Ln = Dy, Eu) phosphors with color-tunable were prepared through solid-state reaction. The crystal structures, photoluminescence properties, energy transfer process, decay, and chromaticity coordinates were also investigated. The emission color of Li 2 Y 4 (MoO 4 ) 7 : Ln 3+ (Ln = Dy, Eu) phosphors were tunable from pale yellow to the nearly white position by adjusting the concentrations of Dy 3+ and Eu 3+ ions or converting the excitation wavelength from 353 nm to 391 nm, and η τ could reach 49.33% when y = 0.60. These results indicated that Li 2 Y 4 (MoO 4 ) 7 : Ln 3+ (Ln = Dy, Eu) may be served as color tunable phosphors.
