摘要
用传统的固相合成法合成了共掺杂稀土离子Eu^3＋、Sm^3＋的红色长余辉材料CaTiO3：Pr，通过对激发、发射光谱、紫外-可见吸收光谱、热释光（TL）的分析，研究了Eu^3＋、Sm^3＋对其发光性能的影响，得出在样品中存在Eu^3＋、Sm^3＋向Pr^3＋的能量传递现象，它改善了材料的发光性能，最后在文中讨论了可能的能量传递途径。
Red phosphor CaTiO3：Pr co-doped with Eu^3＋, Sm^3＋ was synthesized by solid reaction route. The samples were characteristic by XRD, PL, TL, UV-vis. We researched the influence of Eu^3＋. Sm^3＋ on the fluorescent property of CaTiO3： Pr. The results indicate the energy transmit in the sample from Eu^3＋ or Sm^3＋ to Pr^3＋ in CaTiO3： Pr.RE. This phenomenon boosts the fluorescent performance of CaTiO3：Pr.RE. At last, we discussed the possible way of the energy transmit.
