Multi-color luminescence evolution of La2Zr3(MoO4)9:Ln3+ (Ln3+ = Dy3+ and/or Eu3+) nanocrystalline phosphors for UV-pumped white light-emitting devices

The luminescence color of La2Zr3(MoO4)9:Ln3+ (Ln3+ = Dy3+ and/or Eu3+) can be turn from blue-white, white to orange-red by adjusting the doping concentration and the relative ratio of Dy3+ to Eu3+ in La2Zr3(MoO4)9 host lattice to some extent.276
