“…The intensity of the sharp peak ~ 1380 cm −1 increases with Al 2 O 3 increment due to B-O asymmetric vibrations in BO 3 and BO 2 O units and indicates BO 3 increment with the increase in Al 2 O 3 mol percentage [29,31]. Another sharp band at ~ 1607 cm −1 is due to bending vibrations of O-H groups [31,33].…”

Glass composition (30 − x) SrO-xAl 2 O 3-69.5B 2 O 3-0.5CuO (0 ≤ x ≤ 15 mol%) captioned as SABC was prepared by the conventional melt quenching technique. Peak-free X-ray diffractograms and homogeneous plain SEM image confirm the glassy nature of the prepared samples. EPR and optical absorption spectral studies were carried out to understand the effect of modifier oxide (SrO) and transition metal (TM) ion Cu 2+ in the glass network. From the EPR spectra, spin-Hamiltonian parameters were evaluated. It was observed that g ∥ > g ⊥ > g e and A ∥ > A ⊥ suggest that the ground state of Cu 2+ is d x 2 −y 2 (2 B 1g state) and the site symmetry around Cu 2+ is tetragonally distorted octahedral. The optical absorption spectra revealed a broad absorption for all the glass samples. This band is assigned to 2 B 1g → 2 B 2g transition. From optical absorption spectra, optical band gap and Urbach energy values were calculated. The FTIR and Raman spectral studies showed that the glass network consists of BO 3 and BO 4 structural units.

“…Currently, in medical, industrial, and academic applications, glasses containing transition metal oxides have great interest and more attractive [1][2][3][4][5][6][7][8]. Most of the previous studies confirm that the optical characterization of this type of glasses may be changed with addition of different transition metal oxides with different concentrations.…”

In the present study, the optical characterization of borate glasses with composition 35Li 2 O − 10ZnO − 55B 2 O 3 − xMnO 2 : x = 0, 0.5, 1.0, 1.5, and 2.0 wt% has been investigated. The absorption spectra measurements within the wavelength domain 200-1000 nm have been carried out. The optical energy gap of the investigated samples using the absorption spectrum fitting (ASF) model has been calculated. The molar refraction, molar polarizability, reflection loss, optical transmission for the samples were estimated. The metallization criterion, dielectric constant, refractive index, and energy band metallization criterion for the studied glasses were estimated. Magnetic property measurements for all glass samples were carried out at 300 K. Additionally, the prospects of gamma-ray interactions with the investigated glasses have been achieved through studying the total mass attenuation, coherent, Compton, photoelectric, and pair production interactions at photon energy in the range of 0.356-1.330 MeV. Results reveal that the optical and magnetic properties of the investigated glasses change with changing the MnO 2 concentration. Studied glasses can be used as a candidate for optical fiber and optical devices application. In the other hand, at lower gamma photon energy range, the photoelectric absorption dominates with the glasses, while as the energy increases, the probability of Compton scattering and pair production become the most dominate interactions.
