“…These measurements were made to make a comparison between the experimental data that was gained in the present work with the previous research [22][23][24][25]. FTIR spectra of the glass-ceramic [26]. The band position located at 576 cm −1 was due to the Si-O bending vibration modes [27].…”

Willemite- (Zn2SiO4-) based glass ceramics doped with various amounts of europium oxide (Eu2O3) were prepared by solid state melting and quenching method. Effect of sintering temperature (600–1000°C) on structural and morphological properties of the doped samples was investigated. Phase composition, phase evolution, functional groups, and microstructure analysis were, respectively, characterized using X-ray diffractometer (XRD), fourier transform infrared spectroscopy, field emission scanning electron microscopy (FE-SEM), and energy-dispersive X-ray. XRD analysis detected the presence of rhombohedral crystalline phase in the doped samples sintered at different temperatures. FE-SEM and bulk density results confirmed that doping of the willemite with Eu2O3effectively enhanced densification. The microstructural analysis of the doped samples showed that the average grain size increased with the increase of sintering temperature.

“…The density is affected by the structural softening/compactness, the changes in geometrical configuration, coordination number of the ions. The density of the glass matrix partially affects the bulk properties of the glass samples like linear refractive index [23]. The values of density (ρ) measured for the present glass samples are listed in Table 1.…”

“…Density was used in calculation of several important properties such as refractive index, elastic properties, and thermal conductivity. The density is affected by the structural softening/compactness, changes in geometrical configuration, coordination number, cross-link density, and dimension of interstitial spaces of the glass [5].…”

Erbium nanoparticles (NPs) doped zinc borotellurite glasses have been prepared by conventional melt-quenching technique with the chemical composition{[(TeO2)0.70(B2O3)0.30]1-x(ZnO)x}1-y(Er3O2)y(wherey=0.005,0.01,0.02,0.03,0.04,0.05). The structural properties of the prepared glasses were determined via X-ray diffraction (XRD) analysis and FTIR analysis. It was confirmed that the prepared glasses are amorphous. The bonding parameters of the glasses were analyzed by using FTIR analysis and were confirmed to be ionic in nature. The refractive index increases as the content of erbium NPs increases. The optical absorption spectra revealed that fundamental absorption edge shifts to longer wavelength as the content of erbium NPs increases. The value of band gap had been calculated and shown to be decreased with an increase content of erbium NPs. The Urbach energy was shown to be linearly increased with an increase content of erbium NPs oxides.
