Abstract
The subject of the study was to determine the effect of erbium ions (Er3 +) on the structure of tellurite glasses. For this purpose, the positron annihilation lifetime and Raman spectroscopy were used. Changes in positron lifetime parameters and the corresponding intensities have been linked to the geometry and the number of free spaces, the pores of which vary from several angstroms to several dozen nanometers under the influence of erbium (Er3+) doped. Experimental spectra of positron lifetime have two constituent lifetimes of positrons − τ1 and τ2. The interpretation of lifetime components was based on the two-state trappingmodel. The application of Raman spectroscopy allowed to assess that the introduction of erbium ions into the tested phosphate tellurite glasses leads to depolymerization of the tellurium subnet. © 2020 Elsevier B.V.
