Luminescent property of a novel green emitting phosphor Sr3Bi(PO4)3:Tb(3+).
A novel green phosphor Sr3Bi(PO4)3:Tb(3+) is synthesized by a high temperature solid-state method at 1250°C in air, and its luminescent property is investigated. The powder X-ray diffraction patterns of Sr3Bi(PO4)3:Tb(3+) indicate a similarity crystalline phases to Sr3Bi(PO4)3. Sr3Bi(PO4)3:Tb(3+) shows green emission under the 376 nm radiation excitation, and the prominent luminescence in green (543 nm) due to the (5)D4-(7)F5 transition of Tb(3+). For the 543 nm emission, the excitation spectrum has several excitation bands, and the strongest excitation peak locates at 376 nm. The emission intensities of Sr3Bi(PO4)3:Tb(3+) can be influenced by the Tb(3+) doping concentration, and can be achieved the maximum at 0.1 mol Tb(3+). Moreover, the concentration quenching effect of Tb(3+) in Sr3Bi(PO4)3 can be observed. The CIE color coordinate of Sr3Bi(PO4)3:0.1Tb(3+) is (0.299, 0.542).
