摘要

The impact of Yb2O3 on the structure, physical, FTIR, mechanical, and radiation absorption capacity of bismosilicate glasses was investigated. The composition of glasses were 10LiF-(25-x)CaO–15Bi2O3–50SiO2–xYb2O3, where x = 0 (GYb1), 0.125 (GYb2), 0.25 (GYb3), and 0.5 (GYb4) mol%. Density (ρ) increased with doping Yb2O3 instead of CaO content, ranging from 4.67 g/cm3 to 4.85 g/cm3. Molar volume (Vm) declined from 24.96 cm3/mol to 24.38 cm3/mol. The field strength of the prepared glasses increases from 1.8032 (cm−2 × 1014) to 4.5686 (cm−2 × 1014) g/cm3 as Yb2O3 content increase from 0.125 to 0.5 mol%. An increase in the absorption band intensity is observed which associated with the Yb2O3 bending modes (Yb–O–Si) with increasing the ratio of Yb3+ ions. As the concentration of Yb2O3 increased, the elastic moduli of GYb glasses improved. Mass (Mac) and linear (Lac) absorption coefficients obeyed the trend: (GYb4)Mac, Lac > (GYb3)Mac, Lac > (GYb2)Mac,Lac > (GYb3)Mac,Lac. The half- value layer (Hvl) and mean-free path (Mfp) obeyed in the following order: (GYb1)Hvl,Mfp > (GYb2)Hvl,Mfp > (GYb3)Hvl,Mfp > (GYb4)Hvl,Mfp. Results confirmed that the suggested GYb glasses can be considered as promising new materials in fields of solid-state devices and radiation protection.
