Abstract:

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 6H_5/2 → 4K_11/2 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 6H_5/2 →4F_11/2; 6H_5/2 →3H_7/2; 6H_5/2 → 4F_9/2; 6H_5/2 → 4D_5/2; 6H_5/2→4K_11/2; 6H_5/2 →6P_5/2; M _19/2; 6H_5/2→4G_9/2; 4I_15/2; 6H_5/2→4F_5/2; 4I_13/2; 6H_5/2 →4I_11/2; 4M_15/2.
