Abstract

The chemical composition of the following glass system 75Li₂B₄O₇-10CdO-(15-x)BaO- xTm₂O₃ (0 ≤ x ≤ 2) mol.% has been fabricated using a traditional melt quenching procedure. The density of the synthesis samples has been measured and it enhanced with the rising Tm₂O₃ content. All the fabricated specimens form glass and the amorphous state have been confirmed the XRD. The spectroscopic investigation indicates an increase in the energy gap from 3.08 to 3.25 eV with increasing Tm₂O₃ concentrations. The refractive index, basicity and static and infinity of dielectric constant were taken place of present investigated. The ultrasonic velocities of the prepared glasses are increased. Consequently, the elastic modulus of glasses has been enhanced. MCNP5, XCOM, and Phy-X/PSD code were used to characterize the efficiency of the fabricated glass against gamma radiation. Indeed, an increase in Tm₂O₃ content in samples correlated with an increase in MAC values. Consequently, the gamma-radiation attenuation rate of the samples was enhanced by the addition of Tm₂O₃, and the protective qualities were improved.
