Abstract: This thesis deals with luminescence and persistent luminescence of Eu2+ activated materials and aims at unraveling the mechanism behind the persistent luminescence, in particular the role of Dy3+ in the physical process leading to persistent luminescence. The second aim of this thesis is the preparation and characterization of persistent luminescence phosphors emitting at different colors, especially yellow and red, where there is a need for better afterglow materials. A range of aluminates, silicates and chloroaluminates host lattices doped with Eu2+ and co-doped with additional rare earths are investigated.
