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 Ti-[VI](3+) and two Ti-[V](3+) environment (square pyramid and trigonal bi-pyramid). The Ti-[VI](3+) 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. (C) 2011 Elsevier B.V.
