“…Additionally, europium oxide ions reduce the molar volume and result in shrinkage in the glass network, which improves the density. The observed increase in density is endorsed to the rise in the hardness of the glass sample [12,13,[33][34][35][36]. The linear deviations in density and molar volume of BTE glasses with the rise in the europium oxide content state that the glass network is exhibits continuously close-packed.…”

The glass series of xEu2O3-5PbO-25TeO2-(70-x) B2O3, where x=0.1 mol% to 0.6 mol% were prepared by employing the conventional melt quenching method. The non-crystallinity of prepared BTE glasses was examined by the X-ray diffraction method. The very important mechanical properties such as elastic moduli, Debye temperature, Poisson’s ratio, fractional bond connectivity, softening temperature, acoustic impedance, and the thermal expansion coefficient of the BTE glasses have been studied by measuring ultrasonic velocity. The experimental results indicate that the calculated parameters strongly depend on increasing Eu2O3 concentration. The elastic moduli of the prepared samples were found to decrease with Eu2O3 concentration and this increases the discontinuity in the glass network.

In this study, the structural chemistry of Fe3+ doped Li2O–Al2O3–SiO2–TiO2 (LAST) glasses has been analyzed utilizing UV-Vis spectroscopy. Optical parameters like absorption and extinction coefficients, indirect and direct optical band gaps, Urbach energy as well as Fermi energy level of samples were estimated via their absorption spectra. Then, it was tried to make a relationship between the variation of mentioned parameters and structural chemistry of different doped samples. Results of the investigation illustrated that even a little change in the microstructure of glassy samples has an effect on optical parameters and accordingly it could be sensible. Furthermore, it was revealed that Fe3+ ions have the role of network forming in the structure of glass by increasing the formation of bridging oxygens (BOs) in the matrix.

“…The optical feature of Dy 2 O 3 doped with borosilicate glasses was also tested via the transmission of UV lights. 116 The addition of Dy 2 O 3 reduced both the UV transmittance and band-energy gaps while enhancing the refractive index. In addition, the Eu 3+ -doped Lu 2 WMoO 9 phosphors demonstrated enhanced excitation and photoluminescence spectra with UV chips (i.e., 365 nm) (Figure 9).…”

In small- and large-scale industries, manipulable optical characteristics are desired. In this regard, rare-earth oxides (REOs) have been providing pragmatic attributes in terms of successful implementations and promising prospects throughout the last few decades. Currently, there is no comprehensive literature review on REOs that can aid researchers in focusing on industry-relevant emerging materials. Therefore, this review reports studies that have been able to experimentally utilize the physical, chemical, thermal, electronic, spectroscopic, and photocatalytic properties of REOs in the optical field. The brief and focused review finds that the most pronounced applications of REOs in the optical field are in white light and laser, while the prospective ground likely lies in optoelectronics, fiber optic applications, and miscellaneous repertoires that incorporate an innovative utilization of an electronic configuration of REOs. From the perspective of this review, the versatility of an REO in the optical field has become prominent and quantified by the successful implementations of REOs in white light and nonwhite light applications. Furthermore, the innovative applications of REOs include but are not limited to the development of solid-state optical devices, optoelectronic systems, and photocatalytic agents. Specifically, their futuristic applications are likely to be led by the development of stronger emission devices and the obtaining of flexible doping characteristics by several ions such as Li+, Eu3+, Dy3+, Nd3+, La3+, Yb3+, etc. at different levels, which will render the pathway for further exploration in this regard. However, the improvement in terms of methodological attributes requires a serious consideration of overcoming the limitation of thermal stability, lack of exploration of several types of lights, photodarkening in critical applications, lack of applicability at a wide range of temperatures, and so on. From an industrial perspective, it can be conjectured from the reported literature that the challenges will be overcome at a large scale within a few years due to the expedited technological advancements of the experimental repertoires, rendering the REO applications in the optical field reasonably economic and commercially viable. In short, this is the first review that objectively considers the applications and prospects of REOs, which will essentially invoke several studies to investigate the specific properties and viability of REOs in the optical field.
