Abstract

Fluorescence of $Dy^{3+}$ and $Tb^{3+}$ and the energy transfer between them in $Na_5TiP_30_{12}$and $Na_4NbP_30_{12}$ glasses have been studied. Concentration quenching of fluorescence occurs in the case of $Dy^{3+}$ at concentrations above 3 weight %, whereas in the case of $Tb^{3+}$, it does not occur up to 5 weight %. The energy transfer from $Dy^{3+}$ to $Tb^{3+}$ is nonradiative and takes place through dipole-dipole interaction.
