Abstract

This work studied novel lanthanum-doped zinc tellurite (TZL) glasses with different (La₂O₃) content for their mechanical, thermal, and γ-radiation shielding abilities. (TZL) glasses with the composition (

28 - x

) ZnO–72TeO₂-

x

La₂O₃, where x = 0:16 mol% were fabricated by melt-quenching performance. The densities of the glasses were increased from 3.13 for TZL-0 to 4.73 TZL-16, whereas the molar volume decreased from 43.994 for TZL-0 to 37.38 for TZL-16. The thermal analysis of the glasses was estimated by differential thermal analyzer (DTA). The increasing La₂O₃ content leads to an increase the longitudinal (

V_{L}

) and transverse (

V_{T}

) velocities. The (V_L) was increased from 4710 to 4925 whereas the (V_T) increased from 2610 to 2655. This behaviour reflects enhanced glass compactness. The

γ

shielding factors have been enhanced by the incorporation of the La₂O₃. Regarding of the

γ

shielding the TZL-16 sample with the composition has a higher superior ability than the other samples. According to these results, the prepared glasses can be used for medical applications.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
