Structural Investigations of Gamma-Irradiated PbO Glasses

Abstract:

The effects of gamma radiations on the optical, physical and structural properties of zinc lead borate xZnO-2xPbO-(1-3x)B₂O₃ and zinc lead borosilicate xZnO-2xPbO-1/2(1-3x)B₂O₃-1/2(1-3x)SiO₂ glasses have been investigated. Differential Scanning Calorimetry (DSC), Ultraviolet-Visible (UV-Vis) and Fourier Transmission Infra-red (FTIR) spectroscopic techniques have been used to compare the properties of samples before and after gamma irradiation by a dose of 2.5 kGy. The variation of density, optical band gap (E_g), IR absorption bands and glass transition temperature (T_g) indicates that the structure of glasses changes due to irradiation. The radiation induced changes created by-ray in the optical, physical and thermal parameters in both the prepared series of glasses have been discussed for their possible application as radiation shielding material.
