Energy Transfer in Er:CeF3 Crystals
-
Abstract
Two Er:CeF3 crystals doped with 1.0 and 1.2 wt.% Er2O3 and one pure CeF3 crystal were grown, their absorption and fluorescence spectra at room temperature were measured. Compared with pure crystal, the emission intensity of Ce3+ in Er : CeF3 decreased obviously, it is the sign of energy transfer from 5d state of lattice Ce3+ to 4f state of Er3+ ions which improves the stimulation emission efficiency of Er3+ ions.
