Properties of Sm3+ doped zinc barium boro-tellurite glass (ZBBT glass) with the formula 10TeO(2)-35B(2)O(3)-30BaO-24ZnO-1Sm(2)O(3) and 35TeO(2)-10B(2)O(3)-30BaO-24ZnO-1Sm(2)O(3) prepared by conventional melt quenching technique and their physical, optical and photoluminescence properties were investigated. The physical properties have been measured using a densitometer kit based on Archimedes' principle. The result of the measurement shows that ZBBT glass with the higher TeO2 concentration have higher value in density and molar volume, but it has the lower value in the lifetime. The UV-VIS-NIR absorption spectra were recorded at room temperature in the wavelength range of 200-2,500 nm. From the measurement, it is known that glass with 10 mol% of TeO2 have a higher absorbance value compared to 35 mol% of TeO2. Seven luminescence bands in excitation spectra represent the transitions from the ground state H-6(5/2) to various excited states. Furthermore, the emission spectra were observed under 403 nm light from the xenon flash lamps, four luminescence bands were observed at 562 nm ((4)G(5/2)-> H-6(5/2)), 598 nm ((4)G(5/2)-> H-6(7/2)), 645 nm ((4)G(5/2)-> H-6(9/2)) and 706 nm ((4)G(5/2)-> H-6(11/2)), intense reddish orange emission was found at 598 nm.
