“…48 Figure 2A shows the UV-vis absorption spectra of the 20FeP, 30FeP, 40FeP, and 50FeP glass samples, respectively, within the wavelength range of 200-800 nm. The optical absorption edge shifts to a higher wavelength as the increase of Fe 2 O 3 content, which could be caused by the formation of NBOs, 49,50 thus weakening the rigidity of the glass network. This result consists with the variation trend of T g as a function of Fe 2 O 3 content (Figure 1B).…”

We investigate the thermal and electrochemical properties of xFe2O3‐(100‐x) P2O5 glass (x = 20, 30, 40, and 50 mol%) and 50Fe2O3‐50P2O5 (50FeP) glass‐ceramics as anodes for lithium‐ion batteries (LiBs). The results show that both the glass transition temperature and the energy bandgap monotonically decrease with the increasing Fe2O3 while a critical Fe2O3 content of 30 mol% is found to give glass the highest thermal stability, the largest capacity at 1 Ag‐1, and the lowest charge‐transfer resistance before cycling. Moreover, Fe3(P2O7)2 crystals formed during heat treatment in 50FeP glass effectively enhances the electrochemical properties. The optimum heat treatment condition for 50FeP glass is found at 1033 K for 4 h, that is, 1033 K‐4 h sample enables a reversible capacity of 237 mA h g−1 at the end of 1000 cycles at 1 Ag‐1, which is more than 1.5 times higher than that of the 50FeP glass‐based anode. These findings suggest that the Fe2O3‐P2O5 glass‐ceramics hold significant potential for the effective development of new types of glass anodes for future advanced LiBs.

ABSTRACT. Linear, nonlinear optical properties, photon buildup factors, and neutron shielding capability of glasses with chemical composition (65-x)B2O3-10Sb2O3-25Li2O-xBi2O3, where x = 0 (BSLB0) – 20 (BSLB20) mol% with steps of 4 mol% were examined. Molar refractivity (Rmolar) and molar polarizability (αmolar) were increased as Bi2O3 content mol% increase in the examined BSLB-glasses. The values of metallization criterion (Mcriterion) confirmed that the BSLB-glasses were non-metallic materials. The static (εstatic) and optical (εoptical) dielectric constants having the same trend of the refractive index (noptical). Values of optical electronegativity (χ*) were reduced from 0.825 for BSLB0 (Bi2O3 = 0 mol%) glasses to 0.758 for BSLB20 (Bi2O3 = 20 mol%) glasses. The linear electric/dielectric susceptibility (χ(1)) increased from 0.370 to 0.397. The nonlinear optical susceptibility (χ3) and nonlinear refractive index n2optical were enhanced by increasing Bi2O3 content in the BSLB-glasses. The BSLB20 glasses presented the least exposure and energy absorption build-up factors (EBF and EABF) at all considered thickness. BSLB20 sample achieved the best fast neutron removal cross section ( ) shield among all glasses. The total stopping powers (TSP) follows the trend (TSP)BSLB0 < (TSP)BSLB4 < (TSP)BSLB8 < (TSP)BSLB12 < (TSP)BSLB16 < (TSP)BSLB20. The electron absorbing and hence shielding capacity of the BSLB-glasses improves as their Bi2O3 content increase.

Silicate glass is a popular radiation shielding material due to its abundance on Earth. However, due to simplicity of fabrication, tellurite-based optical glass materials became the primary glass network forming, garnering great scientific and technological relevance for their future uses. Previous studies have stated that the silicate and tellurite glass system might be employed in shielding applications, with metal oxide concentrations balanced with SiO2 and TeO2 content. The inclusion of SiO2 and TeO2 in the glass composition reduces the impact of radiation. In electron radiation, electron interaction activities with glass are more substantial in the low electron energy area. Meanwhile, the proton attenuation factors of the glass samples are smaller than the electrons. There is no discernible difference in the fast neutron effective removal cross-section (ΣR) values of the glass samples in neutron radiation. In the studies of tellurite glasses for gamma radiation shielding, the photon interaction parameters change as a function of material density. The measurements show that adding TeO2 to glass samples improved the gamma protection characteristics of the glasses. This review explains the various material compositions and presents a more in-depth analysis of radiation shielding properties in silicate and tellurite glasses.
