A single-phase white light emitting phosphor Ba₃Y(PO₄)₃:Ce³⁺/Tb³⁺/Mn²⁺: luminescence, energy transfer and thermal stability

Abstract

A series of Ce3+/Tb3+, Tb3+/Mn2+ and Ce3+/Tb3+/Mn2+ doped Ba3Y(PO4)3 were synthesized by the high temperature solid state method.

Crystal structure, optical spectroscopy and energy transfer properties in NaZnPO4:Ce3+, Tb3+ phosphors for UV-based LEDs

“…A maximum Ce 3+ / Tb 3+ energy transfer efficiency of 91% was obtained for NZPO:0.05Ce 3+ /0.08Tb 3+ sample which is found to be higher than that of the similar reported orthophosphate phosphors, such as NaBaPO 4 :0.04Ce 3+ / 0.15Tb 3+ (78.8%), 43 NaCaPO 4 0.02 Ce 3+ /0.12Tb 3+ (80%), 44 Ba 3 -Y(PO 4 ) 3 :0.05Ce 3+ /0.45 Tb 3+ (69.9%). 45 Generally, two factors can be responsible for the resonant energy transfer mechanism: the exchange interaction and the multipolar interaction.…”

Synthesis and luminescence properties of Pr3+ ion‐doped Ba3Y(PO4)3 phosphors

“…[ 20 ] Y Chen and colleagues reported a Ba 3 Y(PO 4 ) 3 :Ce 3+ /Tb 3+ /Mn 2+ phosphor for warm white LED applications. [ 21 ] In addition to this, the luminescence behaviour of Pr 3+ ions varied strongly in different hosts and provided red, green, and blue emissions with respect to the various host matrices. To the best of our knowledge Ba 3 Y(PO 4 ) 3 doped with Pr 3+ ions has not been reported, so in this work we studied the synthesis and luminescence properties of a Pr 3+ ion‐doped Ba 3 Y(PO 4 ) 3 phosphor.…”

Crystal Growth, Photoluminescence and Radioluminescence Properties of Ce3+-Doped Ba3Y(PO4)3 Crystal

“…In the last few years, a large number of studies based on the BYP matrix have focused on the tunable visible phosphors doped with rare-earth ions like Eu 3+ , Dy 3+ , Sm 3+ , etc., or temperature-sensing phosphors with Ce 3+ /Eu 2+ /Mn 2+ , Ce 3+ /Tb 3+ , Tb 3+ /Eu 3+ ions, etc. [21][22][23][24][25][26]. Y. Takebuchi et al have reported that the Ba 3 RE(PO 4 ) 3 (RE = Y, La and Lu) crystals showed the intrinsic luminescence peaked at 400 nm under vacuum-UV and X-ray excitation; the X-ray-induced scintillation decay time was several microseconds, and the absolute light yields were estimated to be 960, 1160, and 1220 ph/5.5 MeV under 241 Am α-ray irradiation, respectively [27].…”
