Résumé

The study deals with complex investigation of segregation phenomenon of Eu3+ (View the MathML sourceEuF3) and Tb3+ ions (View the MathML sourceTbF3) in Ba(PO3)2-MgCaSrBaAl2F14 glasses, by using photoluminescence methods, followed by Rayleigh and Mandelstam-Brillouin scattering (RMBS) measurements. It is shown that the local environment of rare-earth ions depends on the ratio of rare-earth concentration and phosphate component content. The results are interpreted in terms of doping-ion segregation model.
