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.

对掺杂 La2O3 的锌碲玻璃的机械和辐射屏蔽特性的深入研究

本文研究了不同La2O3含量的新型掺镧碲酸锌（TZL）玻璃的机械屏蔽能力、热屏蔽能力和γ辐射屏蔽能力。利用熔淬性能制备了（28−x） ZnO-72TeO2-x La2O3玻璃，其中x = 0:16 mol%。TZL-0的玻璃密度从3.13增加到4.73，而TZL-16的摩尔体积从43.994减少到37.38。用差热分析仪（DTA）对玻璃进行热分析。La2O3含量的增加导致材料的纵向（VL）和横向（VT）速度的增加。VL从4710增加到4925，VT从2610增加到2655。这种行为反映了增强的玻璃致密性。La2O3的加入提高了材料的γ屏蔽系数。在屏蔽γ方面，具有该成分的TZL-16样品比其他样品具有更高的优越能力。根据这些结果，制备的眼镜可用于医疗应用。

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.
