Optical, elastic, and radiation shielding properties of Bi2O3-PbO-B2O3 glass system: A role of SnO2 addition

In this paper, we investigate the influence of SnO2 content on the physical, elastic, optical, and radiation shielding properties of the glasses described by the formula of xSnO(2)-(10-x) 60Bi(2)O(3)-30PbO- B2O3 (x = 0, 2, 4, and 6 mol%). The oxygen packing density (OPD) are observed in decreasing trend with the values of 54.93, 54.42, 53.92, 53.41 cm(-3).mol(-1) for x = 0, 2, 4, and 6 mol%, respectively. Moreover, we found that the SnO2 content contributes to enhance the optical properties of the present glasses. The HVL of the glasses was almost constant with a value of about 0.001 cm. However, at the maximum energy (15 MeV), HVL assumes the value of 1.627, 1.621, 1.615, and 1.608 cm for x = 0, 2, 4, and 6 mol%, respectively. Furthermore, the present glasses possess superior photon absorbing capacities compared to several commercial glass and concrete shields. This exemplary shielding capacity shown by these glasses propels them to be as future shielding materials against gamma radiation.
