The concentration impact of Yb3+ on the bismuth boro-phosphate glasses: Physical, structural, optical, elastic, and radiation-shielding properties

In this study, the concentration impacts of Yb3+ on a series of bismuth boro-phosphate (EBiBPxY) glasses are studied. The compositional investigations are done through FTIR spectra. EBiBP0.25Y glass is the most compact one. The EBiBP2Y glass is found to be suitable for sound-resistant purposes from the atomic packing fraction and acoustic impedance evaluations. Two procedures were used to determine the competence of EBiBPxY glasses to shield gamma radiation (simulation technique and theoretical technique). The R-squared values were obtained as 0.99998-1, which indicates the harmony between the values collected by the two techniques. As the Yb2O3 increases, the linear attenuation coefficient (LAC) also increases, leading to the finding that the EBiBP2Y has the biggest LAC at the studied energy ranges. The LAC for EBiBP2Y changed from 97.972 to 0.100 cm(-1), increasing the gamma energy between 0.015 and 15 MeV. The obtained values for the half-value layer (Delta(0.5)) showed that with an increase in Yb2O3, the Delta(0.5) reduced. At 15 MeV, the Delta(0.5) values decreased from 7.650 to 6.928 cm, raising the Yb2O3 concentration in the glass network between 0 and 2 wt%. The Delta(0.5) results emphasized that EBiBP2Y owns the best shielding performance.

Automated summary

This study investigates the concentration impacts of Yb3+ on a series of bismuth boro-phosphate glasses. The results show that EBiBP2Y glass is suitable for sound-resistant purposes and has the best shielding performance against gamma radiation within the studied energy ranges. The R-squared values obtained from two techniques indicate high consistency in the results.
