Fluorescence line narrowing spectroscopy of Eu3+ in TeO2–TiO2–Nb2O5 glass

Abstract

In this work we report time-resolved line-narrowed fluorescence spectra of the 5D0 → 7F0-6 transitions of Eu3+-doped 80TeO2-5TiO2-15Nb2O5 glass obtained at 10 K by using different resonant excitation wavelengths along the 7F0 → 5D0 transition. The wavelength dependence of the 7F1 splitting suggests the existence of a broad distribution of Eu3+ centres possessing a variety of local field environments. The influence of the local coordination ions on the optical properties of Eu3+ has been studied by analysing the dependence of the crystal field (CF) parameters on the excitation energy along the 7F0 → 5D0 transition. © 2008 Elsevier B.V.
