“…When Bi 2 O 3 is added to the glass network up to a 12 mol% concentration, CuO 6 ions rise and various donor ions develop, which tend to overlap with excited states of electrons. These many explanations show that the impurity energy band diffuses into the original band gap, causing the optical band gap to decrease (19) . As the concentration increases up to 12 mol%, the occupancy rate increases; however, as the concentration increases, the octahedral occupancy in the glass matrix decreases.…”

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.

“…Nonetheless, a reversal in conductivity is noted above 12 mol% TiO 2 . As modifications, Ti 4+ ions occupying octahedral locations in the glass network will enhance by up to 12 mol% of TiO 2 the concentration of dangling bonds produced by lead ions and Ti 4+ ions with different cations in the existing glass samples (24,25) . The primary factors contributing to the improved structural, optical, radiation shielding, and dielectric properties of current glasses are the atomic radius of Ti 4+ ions, their trivalent oxidation state, the density of the glasses, the intermolecular force between the Ti 4+ ions and Bi 3+ , Pb 2+ , Si 4+ and B 3+ ions, the number of non-bridging oxygens within the glasses, and the octahedral tendency of Ti 4+ ions within the glasses.…”

Objective: The principal aim of this investigation was to assess the impact of bismuth oxide on the optical properties, radiation shielding characteristics, and dielectric behavior of lead borosilicate glasses doped with titanium oxide at a low concentration. Method: We intended to utilize the conventional rapid melt quenching method to produce glasses with the following chemical composition: 25 PbO+ 15 B2O3 + 0.1 TiO2 + (59.9-x) SiO2 : x Bi2O3(0≤x≤12). Findings: XRD and SEM analyses were used to confirm the samples' non-crystalline properties, while DTA investigations were used to evaluate the samples' ability to form glass. The numerous structural elements were identified through the utilization of FT–IR and Raman analyses. The optical characteristics of glasses are determined by optical absorption studies. The findings derived from optical absorption spectral analyses revealed a progressive increase in the concentration of octahedral Ti4+ ions with the mol% Bi2O3 concentration. In order to analyse the glasses' dielectric properties, an impudence analyser was employed. The results obtained from these inquiries indicate that glasses do contain Bi2O3 at concentrations lower than 12 mol% experience a progressive increase in dielectric constant values. Further investigation is conducted into the radiation shielding properties of the glasses. Novelty: The findings indicate that the values of the glasses' optical band gap, radiation shielding ability, dielectric constant, and thermal stability are all directly correlated with their Bi2O3 concentration. Keywords: FTIR, Raman, OBG, MAC, Activation Energy
