Abstract
In the present study, the optical characterization of borate glasses with composition 35Li2O − 10ZnO − 55B2O3 − xMnO2: 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 MnO2 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.
Highlights
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
The probabilities of gamma-ray interactions with the investigated glasses have been achieved through studying the total mass attenuation using XCOM program
Summary
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]. Oxide glasses have growing importance due to their application in low-loss optical fibers, as the dispersion properties changed with the composition. Borate glasses considered as one of the most attractive, brilliant, and preferred host glass former materials It is a prime constituent of numerous large volume industrial glasses [10,11,12,13]. This is because, when alkali oxides add to the covalent boron oxide amorphous system, a significant change will be occurred, resulting in the creation of anionic sites that accommodate the modifying alkali cations [14, 15]
