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 4I15/2→4F7/2, 2H11/2, 4S3/2, 4F9/2, 4I9/2, 4I11/2 and 4I13/2, respectively. The emission spectra of glasses were also investigated and discussed in term of energy level of Er3+ ion in glass matrices.

Comprehensive study of electronic polarizability and band gap of B2O3–Bi2O3–ZnO–SiO2 glass network

“…16 While the oxygen packing density decreased due to the nonbringing oxygen atom, which increased due to the higher atomic number of Bi 3þ in the glass system. 17 The refractive index was used to find the suitability of the glass materials to be used for optical devices. Refractive index was calculated by using the relationship between the band gap energy.…”
