Energy transfer phenomena in Tb3+, Eu3+ activated LiNaY2F8: Gd3+
- 1. Clermont-Ferrand-2 Univ., 63 - Aubiere (France)
Description
Energy transfer phenomena in the system LiNaY1.8Gd0.2F8: Tb3+, Eu3+ have been investigated. At 300 K and 77 K, excitation into the Gd3+ ion results in mainly Tb3+ or Eu3+ emission. It is shown that the excitation energy migrates from the Gd3+ ion to the Tb3+ (5D4) or Eu3+ (5D0) acceptor. The energy levels involved in the energy transfer and the Gd3+ fluorescence decays are discussed considering the existence of two sites for the Gd3+ ion in this material
Abstract (French)
Lorsque les deux ions Gd3+ et Tb3+ ou Gd3+ et Eu3+ coexistent dans LiNaY2F8, des transferts d'energie Gd3+ → Tb3+ et Gd3+ → Eu3+ sont mis en evidence; ils font intervenir essentiellement les niveaux finaux 5D4 de Tb3+ ou 5D0 de Eu3+. La cinetique de la fluorescence de l'ion Gd3+ est decrite en tenant compte de l'existence de deux sites cristallographiques pour l'ion Gd3+ dans ce materiauAdditional details
