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.

“…According to the results obtained for glasses based on germanium dioxide, the intensity ratio of these excitation bands significantly depends on the glass composition. Ramesh et al [ 50 ] showed that in germanate glasses with PbO the bands related to 7 F 0 → 5 L 6 and 7 F 0 → 5 D 2 transitions of Eu 3+ ions are equally intense. On the other hand, for the same glass systems where PbO was replaced by Bi 2 O 3 , the intensity of the band located at 464 nm ( 7 F 0 → 5 D 2 ) is two times stronger than that centered at 393 nm ( 7 F 0 → 5 L 6 ).…”

Glasses containing two different network-forming components and doped with optically active ions exhibit interesting properties. In this work, glass systems based on germanium dioxide and boron trioxide singly doped with lanthanides (Eu3+) and transition metals (Cr3+) ions are research subjects. Optical spectroscopy was the major research tool used to record excitation and emission spectra in a wide spectral range for studied systems. The emitted radiation of glasses doped with Cr3+ ions is dominated by broadband luminescence centered at 770 nm and 1050 nm (4T2 → 4A2). Interestingly, the increase of concentration of one of the oxides contributed to the detectable changes of the R-line (2E → 4A2) of Cr3+ ions. Moreover, EPR spectroscopy confirmed the paramagnetic properties of the obtained glasses. The influence of molar ratio GeO2:B2O3 on spectroscopic properties for Eu3+ ions is discussed. The intensity of luminescence bands due to transitions of trivalent europium ions as well as the ratio R/O decrease with the increase of B2O3. On the other hand, the increase in concentration B2O3 influences the increasing tendency of luminescence lifetimes for the 5D0 state of Eu3+ ions. The results will contribute to a better understanding of the role of the glass host and thus the prospects for new optical materials.

“…Moreover, the luminescence lifetime for glass with BaO is significantly longer than the value of the lifetime for the 5 D 0 state for heavy metal oxide systems doped with Eu 3+ ions [ 86 , 87 , 88 , 89 ]. Also, the results obtained for glasses containing with Er 3+ ions indicate that among our studied samples the glasses with BaO are the best materials, that may be applied as near-infrared broadband amplifiers.…”

The effect of oxide modifiers on multiple properties (structural and spectroscopic) of phosphate glasses with molar composition 60P2O5-(10−x)Ga2O3-30MO-xEu2O3 and 60P2O5-(10−y)Ga2O3-30MO-yEr2O3 (where M = Ca, Sr, Ba; x = 0, 0.5; y = 0, 1) were systematically examined and discussed. The local structure of systems was evidenced by the infrared (IR-ATR) and Raman spectroscopic techniques. The spectroscopic behaviors of the studied glass systems were determined based on analysis of recorded spectra (excitation and emission) as well as luminescence decay curves. Intense red and near-infrared emissions (1.5 μm) were observed for samples doped with Eu3+ and Er3+ ions, respectively. It was found that the value of fluorescence intensity ratio R/O related to 5D0→7F2 (red) and 5D0→7F1 (orange) transition of Eu3+ ions depends on the oxide modifiers MO in the glass host. However, no clear influence of glass modifiers on the luminescence linewidth (FWHM) was observed for phosphate systems doped with Er3+ ions. Moreover, the 5D0 and 4I13/2 luminescence lifetimes of Eu3+ and Er3+ ions increase with the increasing ionic radius of M2+ (M = Ca, Sr, Ba) in the host matrix. The obtained results suggest the applicability of the phosphate glasses with oxide modifiers as potential red and near-infrared photoluminescent materials in photonic devices.
