摘要：
A series of Dy3+ and/or Sm3+ ions doped NaLa(WO4)(2) phosphors have been synthesized by a solvothermal method. The phase, microstructure and luminescence of Dy3+ and/or Sm3+ ions doped NaLa(WO4)(2) phosphors have been investigated. The XRD patterns obviously indicate that Dy3+ and/or Sm3+ ions doped NaLa(WO4)(2) phosphors have the tetragonal scheelite structure. The SEM images show that the synthesized phosphors have the cubic morphology. The overlap between the emission spectrum of Dy3+ and the excitation spectrum of Sm3+ suggests possible energy transfer from Dy3+ to Sm3+ in NaLa(WO4)(2): Dy3+/Sm3+ phosphors and the energy transfer is confirmed by the decreases of Dy3+ emission intensity and the increases of Sm3+ emission intensity for NaLa(WO4)(2):Dy3+/Sm3+ phosphors. On the basis of luminescent properties, the possible energy transfer mechanism has been speculated. (C) 2017 Elsevier B.V. All rights reserved.
