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.

We fabricated Pr 3+ -activated glasses having a composition of 10SrO-5Al 2 O 3 -85TeO 2 (PSAT) for potential use as radiation detectors, and their photoluminescence (PL) and X-ray-induced scintillation properties were then characterized. The PSAT glasses showed several emission peaks in their PL spectra owing to the 4f-4f transitions of Pr 3+ . Furthermore, they exhibited typical PL decay times (0.09-0.86 ms), where the decay originated from the 4f-4f transitions of Pr 3+ . In the scintillation spectra of the PSAT glasses, three peaks at approximately 480, 618, and 636 nm were observed. The scintillation decay times were 0.747-0.840 ms, corresponding to the 4f-4f transitions of Pr 3+ . Furthermore, the PSAT glasses showed afterglow levels of 352-521 ppm, and the lowest afterglow level (352 ppm) was comparable to that of Tl-activated CsI single crystal.

“…Although it showed high quantum efficiency, its X-ray induced luminescence (XRL) properties were poor. 20) The reasons for this are discussed based on the Judd-Ofelt analysis, that is used to understand the probability of the f-f transition and also by the use of vacuum ultraviolet excited emission spectroscopy to understand the transition efficiency of excited free electrons in the conduction band to the emission center. The PL quantum yield of the 1Eu 2 O 3 -50BaF 2 -xAl 2 O 3 -(50-x)B 2 O 3 glasses increased with increasing x, but the XRL intensity decreased.…”

Glass has several advantages over single crystals and transparent ceramics, including easier formability, increased productivity, and higher versatility in composition. However, the scintillation properties should be further enhanced for practical applications. Herein, we focused on fluoroborate glass, which has a high quantum yield. The xCeF3–(50-x)BaF2–25Al2O3–25B2O3 glass showed luminescence quantum efficiency up to 83 % with a broad peak at 380 nm, and its concentration in the quantum yield was remarkably low. The lifetime of the X-ray-induced luminescence was also insignificant to the concentration. The light yields were obtained from the pulse height spectrum: for gamma rays from 241Am, up to 411 photons/MeV; and for neutrons with 252Cf as the source, up to 1717 photons/n were observed. The performance of glass for thermal neutron detection using inexpensive natural abundant B2O3 was notably good. Thus, the possibility of developing an inexpensive glass scintillator has been presented here.
