Criterion on f-f transition emission of europium (II) and its application in complex fluorides

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.
