Investigation of gamma radiation effect on bismuth borate glasses doped with europium oxide and silver chloride

Europium doped Bismuth Borate glasses were prepared by melt quenching technique, the structural and optical properties are studied before and after the gamma radiation. The X-Ray diffraction pattern confirms the amorphous nature of the prepared samples. Fourier transform infrared spectra show structurally it is not changed with few bands slightly red shifted. In the UV-Visible studies there are no extra peaks. The band gaps and Urbach energy is changed a little in rare earth and silver doped samples. The base glass and with 0.3mol% of Eu₂O₃ exhibit no significant change after the gamma radiation. (author)
