| 摘 要： | 将不同荧光性能的铽(Tb)、镨(Pr)离子分别与铕(Eu)离子混合，以三异丙氧基稀土的形式掺杂P(MMA-CO-St)共聚物，研究Eu^3 ／Tb^3 和Eu^3 ／pr^3 共掺杂P(MMA-CO-St)的荧光性能的变化情况．结果表明，Eu^3 ／Tb^3 掺杂的P(MMA-CO-St)中，Tb^3 作为能量给予体，Eu^3 作为能量接受体，能量转移的结果使Eu^3 特征荧光显增强；Eu^3 ／pr^3 掺杂的P(MMA-CO-St)中，Eu^3 的能量向pr^3 转移，致使Eu^3 的特征荧光猝灭，pr^3 的荧光略为增强．

| Abstract: | The triisopropoxyl europium and terbium or praseodymium were mixed and doped into P(MMA-co-St). Fluorescence properties of Eu~(3+)/ Tb~(3+) or Eu~(3+)/ Pr~(3+) ions (co-doped) P(MMA-co-St) were studied. The results show energy transfer occurs from a donor to an acceptor. Tb~(3+) ion behaving as an energy donor transfers energy to Eu~(3+) ion behaving as an energy acceptor in Eu~(3+)/ Tb~(3+) ions co-doped P(MMA-co-St), resulting in a remarkable increase in the Eu~(3+) characteristic fluorescence. Eu~(3+) ion transfers energy to Pr~(3+) ion in Eu~(3+)/ Pr~(3+) ions co-doped P(MMA-co-St), resulting in a quenching of Eu~(3+) ion fluorescence and a increase of Pr~(3+) ion fluorescence. |
