| Abstract | Bi 3+ /Eu 3+ co-activated Sr3Lu2(BO3)4 was successfully synthesized via a solid state reaction. The optimal concentration of Bi 3+ ,Eu 3+ and Bi 3+ /Eu 3+ are 1 mol%, 60 mol% and 1 mol%/20 mol%, respectively. The emission spectra of Sr3Lu2(BO3)4:Bi 3+ ,E u 3+ gives three peaks located at 405 nm, 489 nm which were attributed to Bi 3+ S6 (blue) and C2 (green) site symmetry, respectively and 610 nm which was ascribed to Eu 3+ ( 5 D0 → 7 F2) transition. The emission intensity of Bi 3+ decreases with increasing Eu 3+ content which indicates that a efficient energy transfer occurred in the Sr3Lu2(BO3)4 host. The relative intensity of Sr3Lu1.79(BO3)4:0.01Bi 3+ ,0.20Eu 3+ excited at 327 nm and 370 nm was remarkably enhanced by 201% and 265%, respectively, via the energy transfer from Bi 3+ to Eu 3+ . The results indicate that Sr3Lu2(BO3)4:Bi 3+ ,E u 3+ is a potential |
