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Eu3+/Tb3+和Eu3+/Pr3+共掺杂P(MMA-co-St)的荧光性能的变化情况.结果表明,Eu3+/Tb3+掺杂的P(MMA-co-St)中,Tb3+作为能量给予体,Eu3+作为能量接受体,能量转移的结果使Eu3+特征荧光显著增强;Eu3+/Pr3+掺杂的P(MMA-co-St)中,Eu3+的能量向Pr3+转移,致使Eu3+的特征荧光猝灭,Pr3+的荧光略为增强.
Tb (superscript 3 +) / Tb (superscript 3+) ions were mixed with europium (Eu) by terbium and praseodymium (Pr) ions with different fluorescence properties respectively. And Eu3 + / Pr3 + co-doped P (MMA-co-St). The results show that Tb3 + is the energy donor in Eu3 + / Tb3 + doped P The energy of Eu3 + / Pr3 + doped P (MMA-co-St) shifted to Pr3 +, resulting in the quenching of the characteristic fluorescence of Eu3 + and the increase of the fluorescence of Pr3 + .
