| 摘 要： | 使用高温常压方法合成了稀土发光材料ＬａＯＢｒ２Ｄｙ＾３＋，Ｔｂ＾３＋，研究了其结构，紫外４主阴极射线激发下的激发与发射光谱，Ｄｙ＾３＋的掺杂可将Ｔｂ＾３＋的＾５Ｄ３能级激光能有地弛豫到＾５Ｄ４能级，从而使５Ｄ４－Ｆ（Ｊ＝０，１）的发射，尤其是＾５Ｄ４－＾７Ｆ５的发射增强，发光亮度提高。

| Abstract: | The rare earth luminescence materials LaOBr: Tb3+Dy3+ were synthesized with high temperature,and the structure and luminescence characteristcs were studied. The codoping Dy3+ may makes the energy of 5D3 of Tb3+ transfer to 5D4 level, which makes the emmision of 5D4-7FJ, specially of 5D4-7F5,enhance obviously, and the tatol brightness is increased by about 40% in comparision with the sample without Dy3+ ions, which is result from energy transfer of diple-diple interaction between Tb3+ and codoping Dy3+. |

| Keywords: | Rare earth luminescence energy transfer LaOBrTb~(3+) Dy~(3+) |
