Among the studied 10BaO-20ZnO-20LiF-(50-<i>x</i>)B<sub>2</sub>O<sub>3</sub>-<i>x</i>Yb<sub>2</sub>O<sub>3</sub> (<i>x</i> = 0.1, 0.5, 0.7, and 1.0 mol%) glasses, the 10BaO-20ZnO-20LiF-49.9B<sub>2</sub>O<sub>3</sub>-0.1Yb<sub>2</sub>O<sub>3</sub> glass showed the highest thermoluminescence intensity, trap density, and trap depth.

The amorphous nature was preserved before and after irradiation. The glass density slightly increased after irradiation.

The transformation of [BO<sub>4</sub>] units into [BO<sub>3</sub>] units and non-bridging oxygens was deduced. The color of the glass darkened after irradiation and the optical absorption intensity enhanced between 250 and 700 nm. The optical bandgap reduced and Urbach energy increased upon <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>γ</mi></mrow></semantics></math></inline-formula>-dose exposure. The electron spin resonance of the irradiated glass exhibited two signals at g = 2.0167 and g = 1.9938, corresponding to the non-bridging oxygen hole center and Boron <i>E’</i>-center, respectively. |
