A significant role of MoO3 on the optical, thermal, and radiation shielding characteristics of B2O3–P2O5–Li2O glasses

TLDR: In this paper , the impact of adding MoO3 to the glasses on their shielding ability was investigated, and the lower value of the (MFP) sample has been detected at a higher MoO 3 concentration and it is good radiation attenuation glasses.

Abstract: The glass system 42.5P2O5–42.5B2O3–( $$15-x$$ ) Li2O– $$x$$ MoO3 $$x$$ = $$(0, 2.5,5.10 \;{\text{and}}\;15$$ ), was fabricated using a melt-quenching technique. Optical features are examined depending on measuring the absorption and transmission of the prepared glasses. The energy gap ( $$E_{{{\text{opt}}}}$$ ), increases from 2.23 to 2.49 e.V. Urbach ( $$E_{u}$$ ), decreases from 0.513 to 0.5 e.V. Basicity, polarizability, electronegativity, and some physical constants are determined. The temperature of the glass transition Tg, increases from 493 to 532 °C, the temperature of onset glass crystallization Tc increases from 493 to 532 °C and the temperature of the crystallization Tp increases from 606 to 636 °C. Radiation shielding properties have been examined by Phy-X / PSD. The impact of adding MoO3 to the glasses on their shielding ability was investigated. The lower value of the (MFP) sample has been detected at a higher MoO3 concentration and it is good radiation attenuation glasses. For radiation protection applications, the investigational glasses had superior characteristics.
