The zinc bismuth barium tellurite glasses system doped samarium oxide with chemical composition of (68–x) TeO₂ – 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 950 ^oC for 1 hour. This research study on spectroscopy properties. In order to study the role of Sm₂O₃ in zinc bismuth barium tellurite glass systems. The results shown that the density increased whereas the molar volume decreased with increasing of Sm₂O₃ concentrations. The optical absorption spectra of glasses were measured in the wavelength range of 500 – 2,000 nm for Sm³⁺ ion, the intensity of all absorption bands increased with increasing Sm₂O₃ content. In addition, the luminescence properties of Sm₂O₃ doped zinc bismuth barium tellurite glass systems were carried out using excitation wavelengths of 403 nm the luminescence peaks around 599  nm.
