Quaternary compositions of polycrystalline Bi1.74Dy0.14W0.12−xScxO3 (x = 0.02, 0.03, 0.04, 0.05, 0.06) solid solutions are synthesized by the solid‐state reaction method. The 4a site symmetry of the space group occupied by Sc3+ ion retains the cubic fluorite‐type over a wide temperature range (450–700 °C) for low Sc3+ content without losing the δ‐phase. Dielectric and ionic conductivity by complex impedance in the frequency range from 0.1 to 100 kHz suggests a temperature‐ and Sc3+‐dependent relaxation process. The ionic conductivity increases with the Sc3+ content over the whole tested temperature range. An oxygen ion conductivity of 0.102 Scm−1 at 700 °C and an activation energy of 0.32 eV are achieved for x = 0.06. Optical properties and Rietveld refinement indicate a bandgap reduction due to a bond length reduction (Bi—O). These materials have potential in photocatalysis and water‐splitting technology due to their UV and visible region absorption capabilities.

“…Several successful studies were conducted in tailoring glass system types and the amount of RE ions to improve the luminescence properties up to the desired range. Among other glass host materials, borate-based glasses showed noteworthy results when doped with Dy 3+ ions. ,,,− ,− The incorporation of borate improves the glass property (i.e., the nonlinear refractive index) and provides stability to the glass matrix. The higher phonon energies and fragility problems of borate-based glasses can be resolved by using alkali elements, and several features such as dynamic luminescence center, amplified afterglow due to f-f ion-trapping shell for a prolonged period, robust excitation band around 454 nm, etc., over other RE ions have made the Dy 3+ ion popular among researchers for a white light generation .…”

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.

A new binary metal borate compound, trilithiumdiyttriumorthoborate, Li 3 Y 2 (BO 3) 3 was successfully synthesized by a solid-state reaction at 1000 °C using the initial reactants of Li 2 CO 3 , Y 2 O 3 , and H 3 BO 3 (molar ratio in the order; 1.5:1:3). The phase, crystallinity and size distribution of Li 3 Y 2 (BO 3) 3 was investigated by X-Ray Powder Diffraction (XRD) and Scanning Electron Microscopy (SEM). It was found that single phase Li 3 Y 2 (BO 3) 3 crystallizes in orthorhombic crystal with refined unit cell parameters of a=8.9228, b=9.5840, c=20.4469Å, Z=9 and represent the space group of Pmmm. Average particle size was calculated as 70 nm by Scherrer's equation. The luminescence properties of Li 3 Y 2 (BO 3) 3 were investigated by using steady state photoluminescence (PL) measurement as a function of temperature between 10 to 300 K. It was observed that the spectra are dominated with the transitions in the visible part of spectrum related to defects present in compound. A relatively low intensity band-to-band transition was also observed at high energy side of the spectrum centred at around 3.33 eV. This peak was decomposed into two close peaks at 3.32 and 3.35 eV using Gaussian fitting. From the temperature behaviour of peak energies of these emissions, the band gap of Li 3 Y 2 (BO 3) 3 was estimated to be 3.35 eV for the first time.
