Borate glasses are one of the appropriate materials combained with rare earth ion for fabricating photonic devices. This article reports on spectroscopic and photoluminescence properties of (65-x) B2O3:15 Na2O:10PbO: 5ZnO:5Li2O: x Sm2O3 glasses (where x = 0.05; 0.1; 0.5; 1.0; 2.0 and 4.0 mol%). The glasses have been prepared using the melt-quenching method with total mass of 20 grams mixed in alumina crucible. The optimum size of 3 mm x 10 mmx 10 mm glasses were obtained by cutting and polishing for absorption, infrared, photoluminescence and excitation spectra investigations. Density, XRD and also energy band gap properties were observed to explain the physical phenomena of the glass samples. The results show that the glass structure of Sm3+ doped borate glass system confirms to the amorphous phase. The addition of Sm2O3 ion in matrix glass from 0.05 mol% to 4.0 mol% causes the absorption intensiy increases. The different pattern occur on photoluminescence spectra, where the highest emission intensity achieved on 0.1 mol% Sm2O3 for 6H5/2 → 4K11/2 transition. Whereas the lowest emission intensity experienced by 4.0 mol% Sm2O3. From photoluminescence spectrum, it is well be known that there are ten transition bands corresponding to 6H5/2 →4F11/2; 6H5/2 →3H7/2; 6H5/2 → 4F9/2; 6H5/2 → 4D5/2; 6H5/2→4K11/2; 6H5/2 →6P5/2; M 19/2; 6H5/2→4G9/2; 4I15/2; 6H5/2→4F5/2; 4I13/2; 6H5/2 →4I11/2; 4M15/2.
