| 摘要: 利用微乳液方法，合成了铈、铽共掺杂的氟镁钾纳米粒子，研究了体系中Ce3+→Tb3+的发光特性以及它们之间的相互作用，结果表明KMgF3∶Ce3+，Tb3+纳米粒子中存在Ce3+→Tb3+的能量传递过程，即Ce3+可以将吸收的能量直接传递给Tb3+离子，使得Tb3+的绿色发光强度大为增加。 |

| Abstract: Nanoparticles of KMgF3∶Ce3+, Tb3+ were prepared by microemulsion method. Luminescence properties and interactions between Ce3+ and Tb3+ were studied.The results show that there is an energy transfer process from Ce3+ to Tb3+ in KMgF3∶Ce3+, Tb3+ nanoparticles, namely, Ce3+ ion can directly transfer the absorbed energy to Tb3+ ion, which makes the green luminescence intensity of Tb3+ ion stronger. |
