Strontium-doped borate glasses: synthesis, structure, optical, and radiation attenuation characteristics

The strontium (Sr) effects on the physical, structural, optical, and radiation protection competence of glassy samples with chemical composition (60- y )B 2 O 3 -20ZnO-10Li 2 O-10PbO- y SrO: 0 ≤ y ≤ 25 mol% have been investigated. These glass samples have been produced using the melt-quenching technique. Amorphous nature of samples confirmed via XRD measurements. Samples' density varied from 3.2824 to 3.8717 g/cm 3 , and molar volume varied from 25.396 to 23.698 cm 3 /mol. The oxygen-molar volume (OMV) increased from 11.543 to 13.940 cm 3 /mol and the oxygen-packing density (OPD) decreased from 86.629 to 71.735 g.atom/l. The optical-band-gap energy changed from 2.79 to 2.91 eV. The mass—(MAC) and linear—(LAC) attenuation-coefficients ordered as: (Sr0) MAC,LAC (Sr25) HVL,MFP . The effective atomic number ( Z eff ) follows the pattern seen above. Results revealed that the investigated glasses were superior to be used as shield materials.
