“…From Figure1, it could be seen that the patterns do not exhibit any diffraction line which confirms the amorphous nature of the glasses. Therefore, this sample can be classified as pure amorphous which shows a good agreement with previous research done elsewhere [18][19][20]. Meanwhile, Figure 2 shows the results of density and molar volume of the glass sample against Er2O3 content.…”

Six samples of borotellurite glasses with system (80-x)TeO2- 10B2O3 - 10PbO - xEr2O3 (x=0.0, 0.5, 1.0, 1.5, 2.0, 2.5 mol%) have been prepared by using the conventional melt-quenching method. Some basic physical parameters such as density and molar volume were measured. The result reveals that the density and molar volume increases with the increases of mol% of Er2O3. The amorphous nature of the glass has been characterized using X-ray Diffraction (XRD) and all glasses are found to be amorphous in nature. The structure was analysed by FTIR spectroscopy. The FTIR spectra were recorded at room temperature in the frequency range from 650 to 4000 cm-1 using Attenuated Total Reflectance (ATR) method. From the IR results, the absorption bands were found to be in the range 667-669 cm-1, 710-712 cm-1, 880-887 cm-1, 981-997 cm-1 and 1190-1204 cm-1 which correspond to the stretching and bending vibrations mode. The absorption peaks around 1386-1388 cm-1 and 3741-3748 cm-1 which ascribed to the hydroxyl-metal bond and hydroxyl-hydrogen bond stretching vibration also have been observed. The FTIR results demonstrate that the existing of erbium in the composition leads to good structural properties thus creating potential for this glass in laser applications.

“…To form a stable glass, addition of at least a glass modifier is needed. Tellurite glass is very attractive mainly because of its low phonon energy, which is about 650-880 cm -1 (Mao et al, 2020), good chemical resistance, good thermal stability, high rare-earth ion solubility, high refractive index, and has low phonon energy of about 700 cm -1 (Jha et al, 2012;Vemasevana et al, 2011).…”

This paper presents a comparison study of absorption spectra of borotellurite glasses with compostion: 20TeO2 – 15Bi2O3 – 3TiO2 – (4-x) Na2CO3 – 1Tm2O3 - xHo2O3 where x = 0; 0.5; 1; 1.5; 2; 2.5 (mol%). All glasses are fabricated using melt quenching method. Absorption spectra were recorded at room temperature in the spectral range of 200 – 1100 nm. Within this range, glass with x = 0 mol % of Ho2O3 shows 2 absorption peaks which corresponds to electronics transition from 3H6 to state to 3F3 and 3H4. For x = 0.5; 1; 1.5; 2; 2.5 (mol%), nine absorption peaks corresponding to electronics transition from 3H6 to state to 5G5, 5G6, 1G4, 1G4, 5F3, 5F4, 5F5, 3F3, and 3H4 are shown. It is shown that absorption at 680 nm and 790 are insensitive to the addition of Ho2O3 in contrast to that at 580 nm and 650 nm.

“…These features have made them widely used as doors, windows, and containers and also for technological applications in communication, medical, and military fields. From the various types of glass available, tellurite glass is found to have some advantages that make it more interesting than the other glass formers, such as low melting point, high refractive index [2], and high rare-earth solubility [3]. Nevertheless, tellurite is also known as a conditional glass former where it can only produce glass with the addition of another chemical.…”

Effects of gamma radiation on the elastic properties of {[(TeO2)0.7(B2O3)0.3]0.7[ZnO]0.3}0.99{Tm2O3}0.01 (thulium doped zinc borotellurite glass) were investigated. Glass samples were prepared using the melt-quenching technique. Density and ultrasonic velocity of glasses before and after irradiation process were measured using Electronic Densimeter MD-300S and Ritec Ram-5000 Snap System, respectively. Next, elastic moduli and Poisson’s ratio of the glasses were calculated. Atomic ring size of the glass network was also calculated to support the attained results. Results show that density varied after radiation and maximised at 20 kGy. This is attributed to the breaking and rearrangement of chemical bonding in the glass network due to radiation. Furthermore, all elastic parameters exhibited an increasing trend that indicated the strengthening of the glass samples as well as increment of its rigidity. Besides that, atomic ring size was found to decrease as radiation dose increased. This indicate that compaction of glass network took place as the samples were exposed to gamma rays which in turn contributed to the elevation of elastic moduli of the prepared glass.
