“…The continuous reduction in EAN values is observed at the region of Compton scattering. And at some specific energies, the EAN values are constant [30]. And, few orders of increase in EAN were observed beyond the 300 keV of energy, which indicates the high order of the photoelectric phenomenon at those energy regions.…”

The goal of the ongoing research was to create resources that were mechanically durable, thermally luminous, and radiation-shielding. In this manner, we intended to synthesize lead borate glasses containing functional groups for yttrium and holmimum. Ho2O3 doped glasses, which are typically used for luminescent purposes, will also be used to investigate the thermoluminescence characteristics under gamma radiation. XRD, SEM, EDX, and DTA techniques are used to examine the samples' structure, chemical analysis, and thermal characteristics. To assess the samples' micro-hardness, the test sample's ultrasonic velocities are measured.The mass attenuation coefficient and order of radiation protection ability are shown by the radiation shielding characteristics of samples. It should be highlighted that Holmium ions alone are responsible for the shielding behaviour. The TL characteristics of the samples were examined at gamma irradiation doses of 5, 10, and 25 kGy. Irradiation increases the TL Intensities that have been observed. The findings show that Ho2O3 is the only factor contributing to the TL phenomenon, and test samples exhibit substantial TL activity. Additionally, samples were examined using the DTA technique for changes in thermal stability. Which also implies that changes in thermal stability are solely dependent on holmium concentration. Overall, the results showed that Y(20-x)Pb10B70:Hox glasses are effective TL materials and strong radiation shielding resources with low thickness values.

To make the interpretation of the complex xCsBr.(100 − x)(CaO:SiO2) glasses easier to study, the structure of glasses in a binary composition CaO–SiO2 is being initially investigated. The changes in the crystallization behavior of glasses and the local environment surrounding silicon atoms could be easily followed using X-ray diffraction (XRD) and nuclear magnetic resonance (NMR) spectroscopy. The XRD pattern of the binary 50CaO–50SiO2 glass showed that its structure was amorphous. But when (CaO:SiO2) is replaced with CsBr, some sharp diffraction lines appear in system of the ternary xCsBr.(100 − x)(CaO:SiO2) glass composition. A Polycrystalline Cs2Ca(SiO3)2 structure is the primary phase in CsBr rich glasses. The results based on transmission electron microscopy (TEM-EDP) and X-ray diffraction pattern (XRD) are in excellent agreement, indicating that crystalline-clustered species develop in glasses enriched with CsBr. Both the NMR and FTIR spectra are clearly defined, and they contain different features that distinguish between different silicate structural subunits. One and two bridging oxygen atoms (BO) can be found in the main SiO4 structural units. Such units become less shielded due to increasing of nonbridging oxygen atoms (NBO) in the silicate network by increasing CsBr at the expense of both SiO2 and CaO. There is a good correlation between the data obtained from FTIR and NMR spectroscopy. Both techniques could differentiate between BO and NBO involved in the silicate structural units.
