Luminescence and energy transfer of white emittingphosphor YAI3（BO3）4：Ce3＋,Dy3

A white emitting phosphor of YAI3（BOa）4：Ce3＋, Dy3＋is synthesized by a solid state reaction, and its luminescent prop- erties are investigated. Its phase formation is carried out with X-ray powder diffraction analysis, and there is no crys- talline phase other than YAO3（BO3）4. YAI3（BO3）4：Ce3＋ can pro...

Summary:A white emitting phosphor of YAI3（BOa）4：Ce3＋, Dy3＋is synthesized by a solid state reaction, and its luminescent prop- erties are investigated. Its phase formation is carried out with X-ray powder diffraction analysis, and there is no crys- talline phase other than YAO3（BO3）4. YAI3（BO3）4：Ce3＋ can produce 422 nm blue emission under 367 nm excitation. The emission spectrum of YAI3（BO3）4：Dy3＋ shows several emission peaks under 350 nm excitation, and the peaks locate at 485 nm, 575 nm and 668 nm, respectively. Emission intensities of Ce3＋ and Dy3＋ in YAI3（BO3）4 are influenced by their concentrations, and the concentration quenching effect is observed. Energy transfer from Ce3＋ to Dy3＋ in YAI3（BO3）4 is validated and proved to be a resonant type via a quadrupole-quadrupole interaction, and the emission color can be tuned from blue to white by tuning the ratio of Ce3＋/Dy3＋. Moreover, the critical distance （Re） of Ce3＋ to Dy3＋ in YAI3（BO3）4 is calculated to be 1.904 um.
