“…However, the peak can be detectible for glass with 0.010 mol % of thulium concentration. At 1200-1800 cm -1 , the peak for [BO 3 ] 0 appears [30]. The bridging oxygen is formed which is validated by the creation of TeO 4 and BO 4 structural units [31], thus it increases the Tm 3+ due to the addition of Tm 2 O 3 into the glass system as it made the peak become shallower [32].…”

The bismuth-boro-tellurite glass has been chosen by various analysts from all around the world due to its advantages and ability the improvement of glass technologies. This paper aims to study the structural and optical properties of the bismuth-boro-tellurite glass system with different amounts of thulium oxide as a glass dopant. Four glass sample from chemical composition of [(B2O3)0.25 (TeO2)0.75]0.75 [(Bi2O3)0.25]1-x [Tm2O3]x (x = 0.000, 0.005, 0.010, and 0.015 mol%) were prepared by melt-quenching method with suitable melting and quenching temperature. The Ultraviolet-Visible Spectroscopy (UV-Vis) was used for recording their optical absorption spectra. These optical absorption spectra were used to determine the optical band gap energy, refractive index, and polarizability of all glass samples. While the structural changes are observed using X-ray diffractometer (XRD) and Fourier Transform Infrared Spectroscopy (FTIR).

“…The rare earth Sm2O 3 structural unit decreases in the area while the ZnO structural unit increases. This happened because of the structural rearrangement processes and the bond breaking that occur in the fabricated samples [19]. As well as the ionization and atomic displacement process that occurs in the glass system.…”

Using the traditional melt quenching method, a zinc tellurite glass system doped with Sm3+ ions and having the following composition: [(TeO2 )0.7 (ZnO) 0.3]1-x [Sm2 O3 ] x , where x = 0.01, 0.02, 0.03, 0.04, and 0.05 molar fraction was synthesized. The structural properties of a fabricated glass system were investigated using Fourier Transform Infrared (FTIR) and X-ray diffraction (XRD) analyses. The results obtained from XRD revealed the amorphous nature of e glass system. FTIR analysis shows the bonding parameters present in the prepared glass system. The physical parameters such as density and molar volume show opposite behaviour. The UV-VIS spectroscopy was employed in order to obtain the optical properties of glass system. The optical absorption spectra were recorded in the wavelength ranging from of 200 to 2000 nm. The optical energy band gap for both direct and indirect transitions are found to be increased on increasing the content of samarium oxide. Other useful optical parameters such as refractive index, molar refraction and Urbach energy are found to be decreased. The photo luminescent spectra displays four emission spectral bands at wavelengths 566, 604, 647 and 710 nm under the excitation wavelength of 404 nm. The recorded transitions correspond to 4 G5/2 → 6 H5/2, 6 H7/2, 6 H9/2 and 6 H11/2 transitions of samarium ions respectively. The observed luminescence spectra ascertain that the studied glasses have potential to serve as laser active medium.

“…This paper will report the effects of barium in a boro-tellurite glass system which concentrates on two properties: (i) physical and structural properties, and (ii) gamma radiation shielding properties. Boro-tellurite was chosen as a base glass in this research because of its unique characteristics such as high transparency, good gamma shielding properties and high thermal resistance when added with heavy metal oxides [8]. It is expected that the addition of barium oxide in boro-tellurite glass would increase the glass density and improve the gamma radiation shielding properties.…”

Boro-tellurite glasses have recently been attracting the attention of several researchers as a tremendous optical device and shielding material. In this work, we have synthesized borotellurite glasses with barium oxide (BaO) by melt quenching technique. The structural and shielding property changes after adding of barium oxide in boro-tellurite glass were studied using Fourier Transform Infrared (FTIR) and Lead Equivalent Thickness measurement (LET), respectively. The results show that the bismuth oxide increases glass density, changes the glass structure, and increases the radiation shielding properties. Changes in the glass structure are due to atomic rearrangements and formation of nonbridging oxygen (NBO). The density of boro-tellurite glass system increased when BaO content increased, which is due to the high molecular weight of BaO and the increasing number of non-bridging oxygen (NBO) atoms in the glass structure. In addition, the mass attenuation coefficient, μm of the glass system increases as BaO concentration increases and the half value layer, HVL and mean free path, MFP of 30BaBTe glass is better than some standard concretes.
