| 摘 要： | 建立了Eu^2^+离子f→f跃迁发射产生的判据运用这-判据预测, 设计并合成了近四十种掺Eu^2^+的复合氟化物, 在这些基质中均观察到Eu^2^+的f-f跃迁尖峰发射。本文对所提供的判据从化学键性质和晶场效应方面作了简要解析, 并对判据的运用条件作了讨论。

| Abstract: | The criterion on 4f7(6PJ) ?4f7(8S7/2) (i.e. f ?f) transition emission of Eu2+ ions was established based on chem. band properties and crystal field effects. By means of the criterion, 40 Eu2+-doped complex fluorides were synthesized. The sharp emissions of f ?f transition of Eu2+ ions were observed in these doped compounds The condition for applying this criterion is discussed. |
