Synthesis and luminescence characteristics of Li2Y4–xEux(WO4)7–y(MoO4)y red-emitting phosphor for white LED

Luminescence and Energy Transfer of Li2Y4(MoO4)7: Ln3+ (Ln = Dy, Eu) Phosphors

“…They crystallized in the tetragonal space group I4 1 /a and these PXRD patterns were coupled well with LYM pure phosphor in Ref. 30 which reflecting that both Dy 3+ and Eu 3+ ions are incorporated into the lattice structure of LYM successfully without any other foreign phase diffraction peaks. However, the main diffraction peaks of LYM: 0.36Dy 3+ /yEu 3+ samples had a little shift to low diffraction degrees with the increase of Eu 3+ doping concentration, while this phenomenon is not obvious in LYM: xDy 3+ samples.…”

“…[26][27][28][29] A series of single-component rare-earth-doped phosphors using Li 2 Y 4 (MoO 4 ) 7 as the substrate material and their luminescence properties have been developed in our previous studies. [30][31][32] While the ET mechanism of multi-component rare earth in this matrix material is still deficient now. To develop a series of color-tunable phosphors with practical application, the ET process has been considered by introducing different rare-earth ions into the matrix simultaneously.…”
