Glasses with the composition 48B 2 O 3 - 13SiO 2 - 7BaO- (32-x) Na 2 O-xY 2 O 3 , (x = 0, 1, 2, 4, and 8 mol %) were synthesized by the melt quenching procedure. There is good transparency in every glass sample. The increase in density (2.825-3.894 gm/cm 3 ) of the present glasses is what triggered the decline in molar volume (25.41-21.80 cm 3 /mol) and the decrease in the Boron-Boron distance (0.475-0.452 nm). The estimated values show that E indi . opt . & E di opt . are 2.317, 2.672, 2.8, 2.98 and 3.1 eV, 2.69, 2.92, 3.05, 3.25, and 3.44 eV respectively, whereas (E u ) values declined. As the Y 2 O 3 increased the refractive index ( n D ) increased. ( n D ) of the synthesized glasses using E indi . opt . & E di opt . were estimated. To find the radiation properties of the suggested glasses, the Phy-X/PSD code was employed. We concluded that the current glasses have better radiation shielding capabilities when employed in such fields. As the Y 2 O 3 replacing ratio increased & sum; R increased.
