• We examine the availability of lithium iron borosilicate glasses doped with ZnO as radiation shielding attenuators; for this, a glass system 64.8B 2 O 3 – 8.5SiO 2 – 1.5Fe 2 O 3 – 25.2 - x Li 2 O— x ZnO x = (0 ≤ x  ≤ 16 mol. %) has been fabricated utilizing melt quenching procedures. As the increase in ZnO density increment from 2.77 to 4.47 g/cm 3 and molar volume decrement 21.71 to 16.03 cm 3  mol −1 , respectively. DTA parameters were improved after the incorporation of ZnO into the glass matrix. FT-IR revealed that BO 3 converts into BO 4 after ZnO is integrated & the structure stiffens as the coherence of the glass network improves. To investigate the impact of ZnO on the optical characterizations of glassy specimens were measured in the ultraviolet–visible, & NIR range. The range of the optical energy increases from 2.88 eV to 3.68 eV, while E u decreases from 0.347 eV to 0.272 eV. The radiation shielding specifications of the glass system were also calculated by Phy-X code. The Lithium iron borosilicate glasses doped with ZnO appeared to be transparent to the visible range and to have good gamma-ray and neutron shielding features, according to the obtained outcomes.
