Abstract

Different concentrations of bismuth oxide (x= 0, 5, 10, 15, 20, 25, 30) are added at the expense of boron oxide in the synthesized glassy matrix containing a fixed concentration of lead oxide. All the prepared samples are characterized using FTIR, UV/Vis. spectroscopic techniques and XRD before and after being exposed to -radiation of doses 8 and 12 Mrad. No changes are observed in the wavenumber positions related to the functional groups of the constituents after irradiation. The optical band gap shows a decreasing trend after irradiation that depends on the irradiation dose. The number of coordinate boron reveals a minor variation in their values correlated to the radiation dose. Besides, all glasses show amorphous nature before and after irradiation indicating that samples can be used for radiation shielding.
