“…Particularly, the addition of AlF 3 , CdF 2 and PbF 2 to heavy metal oxide borate glasses is a fascinating field of study as these additives have a significant effect on the structure, crystallization, thermal and optical properties of the glasses [10][11][12][13]. Incorporating these additives can reduce the phonon energy and increase the overall transparency of the oxyfluoride glasses, both of which are critical for optical applications [14]. Additionally, the substitution of oxygen for fluorine within the lead borate glass structure results in reduced viscosity and melting points, as well as increased electrical conductivity and activation energy [15,16].…”

The glass composition (70-x)PbO–(30-y)B2O3–(x+y)AlF3, where x and y ranges from 0 to 20 mol%, were prepared using the conventional melt-quenching-annealing technique. The structural and thermal properties of the glasses were comprehensively analyzed using techniques like Differential Thermal Analysis (DTA), Dilatometry, Fourier-Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). XRD confirmed the amorphous, non-crystalline structure of the glasses. The glass network was found to be composed of structural units such as PbO4, BO4, BO3 and AlO6 using FTIR spectroscopy. FTIR analysis revealed significant structural changes, including the transformation of BO4 to BO3 units and the increase in non-bridging bonds, particularly with higher AlF3 content. DTA was instrumental in determining characteristic temperatures, such as the glass transition, melting, and peak crystallization temperatures, along with glass stability parameters (∆T, Hr, Tgr) for all samples. The study found that the addition of AlF3 led to a decrease in these characteristic temperatures when replacing B2O3, but an increase when replacing PbO. Variations in the density and thermal expansion of the lead borate glass were observed upon the addition of AlF3, decreasing when substituting for PbO and increasing when substituting for B2O3. These findings provide insights into the properties of oxyfluoride glasses, paving the way for future optimization in their composition for varied applications.

This study investigates the optical and radiation shielding characteristics of different glass systems, such as PbF2, MoO3, Bi2O3, and B2O3, with varied concentrations of PbF2. The glass samples were manufactured by a melt quenching technique, with a composition of 20 Bi2O3 – 10 MoO3 - (70-x) B2O3-x PbF2, where x is a value between 0 and 20 mol%. The optical properties were evaluated using UV-VIS spectrophotometry, while the radiation shielding parameters were calculated using Phy-X/PSD software. The mass attenuation coefficient (MAC) at 0.015 MeV exhibited an increase from 34.101 to 54.190 cm²/g as the quantity of PbF2 rose. At an energy of 15.0 keV, the effective atomic number (Zeff) increased from 74.11 to 76.63, while the half-value layer (HVL) decreased from 0.00263 cm to 0.00188 cm. The values of the optical band gap (Eg) ranged from 2.577 to 2.105 eV, showing a decrease as the PbF2 content rose. The study shows that these glass structures can be utilized in advanced technological applications that demand higher optical and radiation shielding properties, thanks to their improved characteristics with increasing PbF2 content.
