LAUSR

Ce2O3, La2O3 and Nd2O3 and Sm2O3 doped in the cadmium borate host glass were prepared. Some optical and physical properties such as density, molar volume, optical band gap energy, the width of the band tails (Urbach energy) and radiation shielding properties were measured. In addition, the attenuation parameters, are calculated at different photon energies using the XCOM program and practical before and after irradiation. A correlation between the results from density, UV–Vis and FTIR measurements indicates that CdO plays a role as a network modifier and alter within the atomic structure is attributable to the formation of BO4 units. The attenuation parameters are calculated at different photon energies using the XCOM program and measured in experiments. These values show that there is a correlation between theoretical and experimental values. Hence, these results indicate that the samples have gamma-ray shielding in this energy range.
