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.
