“…The IR peaks observed in the ranges of 1062–1067 cm −1 may be due to the stretching vibrations of B–O bonds in BO 4 units from tri-, tetra-, and penta-borate groups [ 46 ]. The two IR peaks in the region of 1118 to 1120 cm −1 and 1162 to 1168 cm −1 in our investigated samples were attributable to TiO 4 tetrahedral units [ 47 ]. Other IR peaks in the spectral ranges of 1241–1248 cm −1 were associated with the presence of asymmetrical stretching vibrations of B–O bonds in BO 3 triangular units from pyro-borate groups [ 47 ].…”

A novel series of glass, consisting of B2O3, Bi2O3, TeO2, and TiO2 (BBTT) containing rare earth oxide RE2O3, where RE is La, Ce, Sm, Er, and Yb, was prepared. We investigated the structural, optical, and gamma attenuation properties of the resultant glass. The optical energy bands, the linear refractive indices, the molar refractions, the metallization criteria, and the optical basicity were all determined for the prepared glass. Furthermore, physical parameters such as the density, the molar volume, the oxygen molar volume, and the oxygen packing density of the prepared glass, were computed. Both the values of density and optical energy of the prepared glass increased in the order of La2O3, Ce2O3, Sm2O3, Er2O3, and then Yb2O3. In addition, the glass doped with Yb2O3 had the lowest refractive index, electronic polarizability, and optical basicity values compared with the other prepared glass. The structures of the prepared glass were investigated by the deconvolution of infrared spectroscopy, which determined that TeO4, TeO3, BO4, BO3, BiO6, and TiO4 units had formed. Furthermore, the structural changes in glass are related to the ratio of the intensity of TeO4/TeO3, depending on the type of rare earth. It is also clarified that the resultant glass samples are good attenuators against low-energy radiation, especially those that modified by Yb2O3, which exhibited superior shielding efficiency at energies of 622, 1170, and 1330 keV. The optical and gamma ray spectroscopy results of the prepared glass show that it is a good candidate for nonlinear optical fibers, laser solid material, and optical shielding protection.

“…This increased the polarizability of the material through the increase in the NBOs produced as a result of TeO3 formation. NBOs are more polarizable than bridging oxygen (BOs) (Salah, 2018;Eevon et al, 2016). The decrease in the refractive index observed may be associated with the substitution of Te 4+ ions with Si 4+ ions which are of lower polarizability than the Te 4+ ions (Gouraud et al, 2015).…”

From the agricultural waste of rice (rice husk), high purity SiO2 with about 98.548 % purity was extracted using a very simple room temperature leaching method. Using the rice husk extracted silicate, a system of silicate borotellurite glasses was fabricated with composition equation [(TeO2)0.7 (B2O3)0.3]1-x (SiO2)x with x= 0.0, 0.1, 0.2, 0.3 and 0.4. The density and molar volume were measured, and Fourier transform infrared (FTIR), X-ray diffraction (XRD) and UV-Vis analyses were performed on the glasses. Both the density and molar volume decreased and the XRD pattern confirmed the glasses' amorphous nature. The FTIR showed the presence of TeO3, TeO4, BO3, BO2O, SiO4, and H3BO3 structural units in the glasses. The concentrations of TeO3, TeO4, BO3 and BO2O structures were determined by the deconvolution of the FTIR spectra using an Origin software. The optical energy band gap, index of refraction, oxygen packing density (OPD), molar refractive index, metallization criterion and polaron radius were determined for the glasses. Based on the glass transparency, high refractive index value (2.3026 and 2.2937) and metallization criterion (0.4109 and 0.4132) of the glasses with x= 0.1 and 0.2 have potential for fiber and optical non-linear applications.

“…Based on the result acquired, the density of the glass samples increases as the concentration of silver oxide increases, which can be related to the addition of dopants in the glass system. In silver-doped glasses, the increment in the density of the glass samples is caused by the substitution of a lighter atom with the heavier atom [38,73]. When lower atomic mass of Te (127.6 g/mol) and Zn (65.38 g/mol) is replaced by the combination of Er (167.3 g/mol) and Ag (107.87 g/mol), the overall atomic mass of the glass sample increases.…”

Melt-quenching method was used to synthesize a series of zinc tellurite glasses doped with erbium oxide and silver oxide. At room temperature, X-ray diffraction (XRD) and density measurement were implemented to characterize the prepared glass samples. The amorphous nature of the glass samples is proven from the XRD spectra obtained in this work. The density of the glass showed an increment trend from 4.4673 to 4.9705 g/cm3 when adding more silver oxide, which can prove that the glass strength is higher. For photoluminescence analysis, blue, green and red emissions were found in the glass series under 375 nm excitation wavelength. According to McCumber theory, higher emission cross-section and higher FWHM are efficient for both broadband amplifier and laser application. More extensive and flatter gain with a maximum gain difference has covered both C and L bands for optical communication, providing a few channels in the wavelength division multiplex network (WDM). The high efficiency of optical amplification is justified with a higher gain figure of merit and larger gain bandwidth. According to McCumber’s theory, all the results proved that 0.03 molar fraction of silver oxide is the most optimum concentration to be applied in the optical application. In Judd-Ofelt analysis, spectroscopic quality factor and shorter lifetime is a crucial parameter for obtaining intense laser transition, strong emission probabilities and encouraging the laser optical transition, which was successfully attained in all glass samples. The present glass system is also applicable for white light application since the standard equal energy point from all glass samples were located near the center of the CIE diagram (0.33, 0.33). In the meantime, higher values of CCT range from 6761 to 6937 K produce light with a better image as compared to lower CCT. Higher CCT is commercially used in LCD (liquid crystal display) and CRT (cathode ray tube) screens. The colour purity is a parameter for better white LED application, whereas low colour purity is for pure white light emission. Therefore, lower colour purity was found around 10.7 around 18.8% in all glass samples.
