Abstract

Reduction processes under irradiation of Ti⁴⁺ ions in aluminoborosilicate glasses have been studied by EPR spectroscopy at 20 K. Different parameters like the [Na]/[Ti] ratio and the integrated dose were analyzed in this work. Simulation of the Ti³⁺ ion EPR spectra has shown three different Ti³⁺ environment attributed to one ^[VI]Ti³⁺ and two ^[V]Ti³⁺ environment (square pyramid and trigonal bi-pyramid). The ^[VI]Ti³⁺ ion environment is observed only for higher [Na]/[Ti] ratios although the two others are observed for all values of the [Na]/[Ti] ratio considered.
