Shielding behavior of V2O5 doped lead borate glasses towards gamma irradiation

► Base lead borate glass together with samples of the same composition doped with varying V2O5 contents were prepared. ► UV-visible and infrared spectroscopy were measured before and after successive gamma irradiation. ► Glass samples are observed to absorb strongly in the UV. ► Infrared absorption spectra indicate the presence of both triangular and tetrahedral borate groups besides the sharing of lead ions in network forming and network modifying sites.
