The zinc bismuth barium boro-tellurite glasses system doped with Eu₂O₃. Which varies europium oxide concentration are 0.00, 0.05, 0.10, 0.50, 1.00, and 1.50 mol% of the composition 30TeO₂ – (38-x) B₂O₃ -10ZnO -2Bi₂O₃- 20BaO - xEu₂O₃ have been synthesized by conventional melt quenching technique. The physical and optical properties were investigated. The results shown that the density and molar volume have no trend as Eu₂O₃ doped in glasses system was found the density of the result glass system increased while the molar quantity increased with the quantity of Eu₂O₃ and when measuring the absorption spectrum in the wavelength range 200 to 2500 nm of glass system found the absorption peak intensity was higher with the concentration of europium oxide.
