The zinc bismuth barium boro – tellurite glasses system doped samarium oxide with chemical composition of 30TeO₂ – (38–x) B₂O₃ – 10ZnO – 2Bi₂O₃ – 20BaO – xSm₂O₃, where x are 0.00 0.05 0.10 0.50 1.00 and 1.50 in mol% have been synthesized by conventional melt quenching technique at room temperature at 1,150 ^oC for 1.5 hours. This research study on physical and optical properties. In order to understand the role of Sm₂O₃ in zinc bismuth barium boro – tellurite glasses systems. The result showed that density and molar volume are no trend which the density between 3.6614 ± 0.0039 to 3.8300 ± 0.0003 gram/ centimeter³ and have a value of molar volume between 32.0099 to 33.8936 centimeter³/mol. The optical absorption spectra of glasses were measured in the wavelength range of 500 – 2,000 nm for Sm³⁺, the intensity of all absorption bands increased with increasing Sm₂O₃ content.
