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.
