Sammanfattning

The existence and effect of different rare earth (R2+/3+/IV) ions in SrAl2O4:Eu2+, R3+ and M2MgSi2O7:Eu2+, R3+ (M: Sr, Ba) persistent luminescence materials was studied with XANES (x-ray absorption near edge structure) measurements at HASYLAB/DESY (Hamburg, Germany) and MAX-lab (Lund, Sweden). The experiments were carried out at 298K for selected rare earth (co-) dopants (Eu2+; Ce3+, Nd3+, Sm3+, Dy3+ and Yb3+). The co-existence of Eu2+ and Eu3+ was observed in all materials. The co-dopants were always in the trivalent form.
