Abstract
Abstract Novel single-phased white-light-emitting and color tunable BaSr2Gd(PO4)3:Dy3+, Tm3+, Eu3+ phosphors were synthesized by solid-state reaction method and characterized with power X-ray diffraction (XRD), photoluminescence excitation (PLE), photoluminescence (PL) and PL delay spectral measurement. Under the excitation of ultraviolet, dual energy transfer, namely, Dy3+ to Tm3+ and Dy3+ to Eu3+, exists in the system of BaSr2Gd(PO4)3:Dy3+,Tm3+,Eu3+. The emission color of these phosphors can be accurately changed from greenish blue to blue via ET of Dy3+ to Tm3+ and from yellowish green to yellow via ET of Dy3+ to Eu3+. Under the excitation at 388 nm, BaSr2Gd0.91(PO4)3:0.04Dy3+,0.03Eu3+,0.02 Tm3+ phosphor showed bright a white light with chromatic coordinate of (0.329,0.349). The as-prepared phosphors have a great potential as a credible candidate for near ultra-violet excited white light emitting phosphor.
