Neutron irradiation effects on optical properties of Sm-doped lead borate glasses

الملخص EN

Sm+3 doped lead borate glass (B2O3 -PbO-Al2O3) samples were prepared with different concentrations of Sm+3 using the normal melt quench technique.

The prepared glass samples were irradiated using (5Ci) 241AmBe neutron source with neutron flux of 4.1E7 n/cm2.sec.

A study of the effect of both Sm2O3 content and neutron irradiation doses on some optical properties of Sm2O3doped lead borate glasses ( B2O3-PbO- Al2O3) have been performed.

Optical parameters such as: the absorption coefficient (α), Urbach’s energy (Eu).

Fermi energy (Ef), direct and indirect optical energy gap (Eogd & Eogind) has been evaluated.
