Ba3Y(PO4)3:Dy3+,Eu3+单基质白光荧光粉的制备与发光性能
Synthesis and Luminescence Properties of Ba3Y(PO4)3:Dy3+,Eu3+ Single Phase White-emitting Phosphor
摘要
Abstract
A series of Dy3+ and/or Eu3+ doped Ba3 Y(PO4 )3 phosphors was prepared via a traditional high temperature solid state reaction to investigate how the luminescent properties of Dy3+ doped Ba3 Y(PO4 )3 phosphor can be tuned by co-doping Eu3+ ions into the host lattice. X-ray diffraction (XRD ), photoluminescence and fluorescence lifetime were used to characterize the as-prepared samples. The results show that all the samples have Ba3 Y(PO4 )3 eulytite cubic structure. Under the excitation of near-UV light, the Ba3 Y(PO4 )3:Dy3+ phosphor shows cool-white emission and the Ba3 Y(PO4 )3:Eu3+ phosphor presents an orange-red emission. For Ba3 Y(PO4 )3:Dy3+,Eu3+ phosphor,warm-white emission with high color rendering index and appropriate correlated color temperature has been obtained by combining red emission of Eu3+with cool-white emission of Dy3+. The luminescence mechanism of Ba3 Y(PO4 )3:Dy3+,Eu3+ phosphor has been tentatively proposed and the prepared Ba3 Y(PO4 )3:Dy3+,Eu3+ phosphor has potential application in white-light-emitting-diodes(WLEDs)filed.关键词
