| 摘 要： | The Ba3Y2（BO3）4：Eu^3＋ phosphor was synthesized using a high temperature solid-state reaction method and the luminescent characteristics were investigated. The emission spectrum exhibited one strong red emission at 613 nm, corresponding to the electric dipole 5D0-TF2 transition of Eu^3＋, under 365 nm excitation. The excitation spectrum of 613 nm indicated that the Ba3Y2（BO3）n：Eu^3＋ phosphor was effectively excited by ultraviolet （UV） （254, 365 and 400 nm） and blue （470 nm） light. The effect of Eu^3＋ concentration on the 613 nm emission of the Ba3Y2（BO3）n：Eu^3＋ phosphor was measured. The results showed that the emission intensity increased with increasing Eu^3＋ concentration, and then decreased. The CIE color coordinates of Ba3Y2（BO3）4：Eu^3＋ phosphor were x=0.641 and y=0.359 at 15 mol.% Eu^3＋.

| Abstract: | The Ba3Y2(BO3)4:Eu3 phosphor was synthesized using a high temperature solid-state reaction method and the luminescent characteristics were investigated. The emission spectrum exhibited one strong red emission at 613 nm, corresponding to the electric dipole 5D0-7F2 transition of Eu3 , under 365 nm excitation. The excitation spectrum of 613 nm indicated that the Ba3Y2(BO3)4:Eu3 phosphor was effectively excited by ultraviolet (UV) (254, 365 and 400 nm) and blue (470 nm) light. The effect of Eu3 concentration on the 613 nm emission of the Ba3Y2(BO3)4:Eu3 phosphor was measured. The results showed that the emission intensity increased with increasing Eu3 concentration, and then decreased. The CIE color coordinates of Ba3Y2(BO3)4:Eu3 phosphor were x=0.641 and y=0.359 at 15 mol.% Eu3 . |
