摘要：
This paper aims to investigate theoretically addition of the Dy3+ content on the optical and radiation attenuation properties of TeO2–ZnO – Na2O–Sm2O3 glasses. The STZNDy1 possesses the greatest molar refractivity (Rm) and molar polarizability (αm) whereas the STZNDy5 possesses the lowest Rm and αm. When Dy2O3 content adds into the glass, the reflection loss sharply increases then it declines up to 1.5 mol.% of Dy2O3 content afterwards it is stable however the optical transmission sharply decreases then it increases up to 1.5 mol % of Dy2O3 content afterwards it is stable. The STZNDy5 and STZNDy6 own the greatest metallization criterion while they own the lowest static dielectric constant and optical dielectric constant. Both linear attenuation coefficient and mass attenuation coefficient of the STZNDy glasses increase with the addition of the Dy2O3 content. The STZNDy1 has the highest half value layers (HVLs) and tenth value layers (TVLs) whereas the STZNDy6 has the smallest HVLs and TVLs. The radiation protection efficiency enhances whereas mean free path declines as Dy2O3 content increases in the glasses. Consequently, the STZNDy6 owns the good radiation attenuation ability in the STZNDy glasses, and adding Dy2O3 increases the radiation attenuation characteristics of the STZNDy glasses. © 2024 The Author
