摘要

The intrinsic goal of this work is to understand the effect of composition change on the physical, mechanical, optical properties and radiation shielding capability of the prepared glassy materials. The glasses have a composition of 25CdO–30Bi2O3–XSm2O3–(45-X)SiO2 (X = 0, 0.5, 1, and 2 mol%). By using X-ray diffraction, the amorphous structure of the produced samples examined and verified. Additionally, the impact of altering the compositions on the interior structure was also investigated using (FTIR), some bridging oxygens (BOs) are converted into non-bridging oxygens (NBOs). Density (ρ) increased from 6.08 to 6.24 g/cm3, whereas the molar volume (Vm) enhanced from 32.72 to 32.80 cm3/mol. The volume deviation (Vo) reduced from 2.868 to 2.57 cm3/mol as Sm2O3 increased from 0 to 2 mol%. All elastic moduli were increased as the Sm3+ ions content increased in the glass networks. The mass (MAC) and linear (LAC) attenuation coefficients followed the trend: (MAC, LAC)GSm0 < (MAC, LAC)GSm0.5 < (MAC, LAC)GSm1 < (MAC, LAC)GSm2. The sample GSm2 verified the lowest values of (HVL) among all GSmX samples. The current GSmX samples better than ordinary concrete and some glasses for radiation attenuation application.
