摘要：

A series of Sm3+ and Dy3+ doped LaBWO6 phosphors were synthesized by high temperature solid state reaction. Recorded XRD patterns proved that the titled compound in a single phase has been obtained. Sm3+ and Dy3+ doped LaBWO6 could emit orange and white light, respectively. The optimal doping concentration of Sm3+ or Dy3+ was experimentally ascertained to be 6 mol%. The critical distance of energy transfer for Sm3+ or Dy3+ doped sample is 1.540 nm. In addition, there is no cross energy transfer between the Sm3+ and Dy3+ ions in the co-doped samples. The results indicated that the electric dipole-dipole interaction is predominant energy transfer mechanism for concentration quenching of Sm3+ or Dy3+ doped LaBWO6 phosphor. The charge transfer band was observed in the excitation spectra of Sm3+ or Dy3+ doped LaBWO6 phosphors. Present investigation indicated that Sm3+ and Dy3+ doped LaBWO6 can be applied in solid state lighting and LaBWO6 is a promising host for display applications. (C) 2014 Elsevier B.V.
