Abstract: Sr3Y(BO3)3:xTm3+,yDy3+ phosphors were prepared by high-temperature solid phase reaction. The phase structure, micromorphology, luminescence properties, energy transfer and CIE coordinates of the samples were investigated by XRD diffraction, SEM and fluorescence spectrophotometer. All results indicated that Sr3Y(BO3)3:xTm3+ phosphors emitted blue light under the excitation of 359 nm UV light and the Tm3+ concentration quenching point was x=0.08(n/n). In Sr3Y(BO3)3:0.08Tm3+,yDy3+ phosphors, with the Dy3+ doping concentration increasing, the Tm3+ luminescence intensity decreased; meanwhile, the Dy3+ luminescence intensity firstly increased and then decreased, and the critical quenching concentration of Dy3+ was y=0.1(n/n). The emitting color could be tuned by changing the doped Dy3+ concertration or the excitation wavelength. There is energy transfer between Tm3+-Dy3+ in the phosphors. When the doping concentration was y=0.15, the energy transfer efficiency was as high as 75.14%, and the energy transfer mechanism is electric dipole-dipole interaction.
