The glass system 42.5P 2 O 5 –42.5B 2 O 3 –( 15 - x ) Li 2 O– x MoO 3 x = ( 0 , 2.5 , 5.10 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 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 T g , increases from 493 to 532 °C, the temperature of onset glass crystallization T c increases from 493 to 532 °C and the temperature of the crystallization T p increases from 606 to 636 °C. Radiation shielding properties have been examined by Phy-X / PSD. The impact of adding MoO 3 to the glasses on their shielding ability was investigated. The lower value of the (MFP) sample has been detected at a higher MoO 3 concentration and it is good radiation attenuation glasses. For radiation protection applications, the investigational glasses had superior characteristics.
