“…In the same perspective, as the amount of Bi 3+ ions in the test glasses increases, so do the other dependent metrics including MFP, HVL, and RPE. CuBi-12 glass was seen to have good values for MAC, MFP, HVL, and RPE; CuBi-0, CuBi-3, CuBi-5, CuBi-8, and CuBi-12 glasses will also be beneficial as shielding glasses (22) . Overall, the concentration of Bi 2 O 3 and the thickness of the glasses are the only factors that affect the radiation protection efficiency and shielding phenomena of the test glasses.…”

Objectives: The primary objective of the present investigation was to examine the impact of Bi3+ ions on the optical, radiation shielding, dielectric and structural characteristics of lead borosilicate glasses doped with CuO. Method: In this view, we planned to utilize the conventional rapid melt quenching method to produce glasses with the following chemical composition: 25 PbO + 15 B2O3 + 0.1 CuO + (59.9-x) SiO2 :x Bi2O3 (0≤x≤12). Findings: The samples' non-crystalline characteristics were validated through XRD and SEM analysis, respectively, while their glass-forming capabilities were assessed through DTA studies. Utilizing the FT–IR and Raman analyses, the numerous structural units were determined. According to the findings of the FT-IR, and Raman analyses, the degree of disorder in the glass network increased. By means of optical absorption experiments, the optical properties of glasses were determined. The results obtained from optical absorption spectral investigations indicated that the concentration of octahedral Cu2+ ions increased gradually as the Bi2O3 concentration increased to 12 mol %. The dielectric properties of the glasses, suggested that the dielectric constant values of glasses containing Bi2O3 in concentrations below 12 mol% increase gradually. Additionally, the radiation shielding properties of the glasses are investigated. The values of radiation protection ability found to be purely function of Bi2O3 concentration. Novelty: The results suggest that the glasses' thermal stability, dielectric constant, optical band gap and radiation shielding ability values purely function of Bi2O3 concentration.
