Functional assessment of various rare-earth (RE) ion types: An investigation on gamma-ray attenuation properties of GeO2-B2O3-P2O5-ZnO-Tb2O3-RE magneto-optical glasses
Abstract
We report the functional assessment of various rare-earth (RE) ion types on gamma-ray attenu-
ation properties of GeO2-B2O3-P2O5-ZnO-Tb2O3-RE (where; RE=0; 1 %Ho, 1 %Pr, 1 %Er, 1 %Nd,
1 %Dy, 1 %Ce) magneto-optical glasses. The elemental fractions and densities of each glass
sample were specified separately for the MCNPX Monte Carlo code. In addition to fundamental
gamma absorption properties, Transmission Factors throughout a broad radioisotope energy
range were measured. According to findings, Holmium (Ho) incorporation into the glass structure
resulted in a net increase of 0.3406 g/cm3, whereas Cerium (Ce) addition resulted in a net in-
crease of 0.2047 g/cm3. The Ho-doped S2 sample was found to have the greatest LAC value,
despite the fact that seven glass samples exhibited identical behavior. The Ho-doped S2 sample
had the lowest HVL values among the glass groups evaluated in this work, computed in the energy
range of 0.015–15 MeV. The lowest EBF and EABF values were reported for Ho reinforced S2
sample with the highes LAC and density values. For all glass samples, a decrease in TF values was
observed depending on the increase in thickness. Among the investigated glasses, Ho and Er
reinforced samples (i.e., S2 and S4) showed the minimum TF values at used radioisotope energies.
It can be concluded that Ho and Er type rare earth elements may provide the most effective
gamma ray absorption properties when they are incorporated into the GeO2-B2O3-P2O5-ZnO-
Tb2O3 system
