摘要：
Sr-3(PO4)(2):Dy3+,Li+ phosphors were prepared using a simple high temperature solid method for luminescence enhancement. The structures of the as-prepared samples agreed well with the standard phase of Sr-3(PO4)(2), even when Dy3+ and Li+ were introduced. Under ultraviolet excitation at 350nm, the Sr-3(PO4)(2):Dy3+ sample exhibited two emission peaks at 483nm and 580nm, which were due to the (F9/2H15/2)-F-4-H-6 and (F9/2H13/2)-F-4-H-6 transitions of Dy3+ ions, respectively. A white light was fabricated using these two emissions from the Sr-3(PO4)(2):Dy3+ phosphors. The luminescence properties of Sr-3(PO4)(2):Dy3+,Li+ phosphors, including emission intensity and decay time, were improved remarkably with the addition of Li+ as the charge compensator, which would promote their application in near-ultraviolet excited white-light-emitting diodes.
