| Abstract: | Eu3+ luminescence is studied in the two polymorphic forms of RbGd3F10: Eu3+. In the phases where Gd3+ is partly replacedby Y3+ in order to obtain an independent variation of Eu3+ concentration, the quenching of Gd3+ luminescence by Eu3+ ions takes place very quickly with increasing Eu3+ concentration. So the transfer between Gd3+ and Eu3+ is very efficient. Besides, an important self quenching occurs as well between Gd3+ ions as between Eu3+ ions, showing strong interactions. |
