Physical, Optical and Luminescence Properties of Er³⁺-Doped Bismuth Borosilicate Glasses

Abstract:

Er³⁺-doped bismuth borosilicate glasses (Bi₂O₃+B₂O₃+SiO₂+Er₂O₃) glasses doped with different Er₂O₃ concentrations (0, 0.50, 1.00, 1.50, 2.00, 2.50 mol%) have been prepared by melt quenching technique and their physical, optical and luminescence properties have been studied. The density of glasses showed the highest value at 4.7358 g/cm³ with 1.00 mol% of Er₂O₃. The optical absorption spectra of glasses were observed seven bands at 488, 523, 543, 654, 801, 975 and 1529 nm which assigned to the transitions ⁴I_15/2→⁴F_7/2, ²H_11/2, ⁴S_3/2, ⁴F_9/2, ⁴I_9/2, ⁴I_11/2 and ⁴I_13/2, respectively. The emission spectra of glasses were also investigated and discussed in term of energy level of Er³⁺ ion in glass matrices.
