This paper investigates the optical properties and radiation shielding performance of borosilicate glasses containing chromium trioxide (CrO3) and strontium titanium oxide (SrTiO3). The optical characteristics, including refractive index, absorption coefficient, and transmission behaviour, were thoroughly analysed to gain insights into the transparency and light-carrying capabilities of the glasses. Additionally, the radiation shielding parameters were obtained by utilizing both FLUKA simulation and the XCOM program. The obtained radiation shielding data were then compared and discussed to assess the effectiveness of the glass compositions as shielding materials against ionizing radiation. The results provide a comprehensive understanding of the optical properties and radiation shielding capabilities of the studied glasses, contributing to the development of novel and efficient materials for radiation protection in various applications, including nuclear medicine, industrial radiography, and space exploration. The findings presented in this study offer valuable information for the design and optimization of borosilicate glasses containing CrO3 and SrTiO3 for effective radiation shielding in neutron-rich environments.

GeO2-doped magnesium-telluroborate transparent glasses were synthesized in the current investigation using the traditional melt-quench procedure. XRD and FT-IR were used to examine the glasses' structural properties. Following the measurement of the density, various physical parameters (including oxygen molar volume, oxygen packing density, etc.) were estimated and examined. From the FTIR results, one can deduce that clear structural alterations are seen which support the presence and conversion of BO3 and BO4 units. This is a result of the glass network forming more GeO4, TeO4, and BO4 units, which means that decreased NBO is forming, and more stiff networks are forming as a result. The increase in the overall stretching force constant of the glasses may also have an impact on the elastic moduli. The optical parameters were studied as optical energy band gap, Urbach energy and refractive index of the fabricated glass. According to the HVL data, the current glasses have a significant ability to lessen the intensity of gamma rays with lower energy. The glass with a small amount of GeO2 has a high HVL, whereas the glass with a higher amount of GeO2 has a lower HVL, as shown by the HVL data. The G5 glass demonstrated its superiority as a shielding glass over the other glass samples (G1–G4). [ABSTRACT FROM AUTHOR]

This study experimentally presents the synthesis and characterisation of a new transparent Eu-doped tellurite matrix glassy composite with the view of predicting its UV and radiation sensing applications. This glassy composite, described by 50TeO 2 –15Na 2 O – 15ZnO – (20-x)PbO – xEu 2 O 3 for x = 0 (TPEu-0), 1 (TPEu-1), 2 (TPEu-2), and 3 (TPEu-3) mol%, was prepared by the well-known melting-and- quenching technique. The glassy nature of the prepared samples was verified by the X-ray diffraction (XED) technique, and the density of the glasses was measured by the Archimedes method. The glasses' optical features were determined from optical transmission and absorption spectra. In addition, the gamma radiation sensing and shielding prowess of the TPEu-X samples was determined from Monte Carlo simulation data using FLUKA code and direct calculations from the NISTXCOM database. The response of the glasses under UV-excitation was also analysed. The melting point and density of the glasses increased as the glasses was enriched with Eu 2 O 3. The density of TPEu-X increased from 5.51 to 5.58 while the melting point grew from 750 °C to 1100 °C Eu 2 O 3 concentration grew from 0 to 3 mol%. The increase in the concentration of Eu 2 O 3 activated crystallization in the glass system. TPEu-1 has the highest optical bandgap energy (3.0 eV) and the lowest refractive index (2.39) among the TPEu-X glasses. The Eu 2 O 3 content of the glasses affected their responses and appearance under UV light. Generally, the glass with the lowest Eu 2 O 3 content possessed the least capacity to shield gamma radiation. The prepared TPEu-3 glass displayed the ability to displace many conventional and non-traditional shields in design of efficient radiation protection systems. [ABSTRACT FROM AUTHOR]
