“…48 Among the different series of 0.5 mol % Eu 2 O 3 -doped alkali oxides-modified borosilicate glasses, the Li 2 O−Na 2 O combination has shown the maximum stimulated emission cross-section and experimental branching ratios for the 5 D 0 → 7 F 2 (614 nm) transition, which makes it a possible runner aimed at a red color center for display devices and visible red lasers. 87 The ZnO-TiO 2 has also proved its potentiality for use as a red upconversion phosphor showing very high red emissions when doped with a ratio of Yb 2 O 3 / Er 2 O 3 = 0.06:0.02. 88 The various spectroscopic parameters, that is, the oscillator strength for the 6 H 5/2 → 6 P 3/2 (400 nm) transition, the stimulated emission cross-section 4 G 5/2 → 6 H 7/2 (600 nm) transition, and the branching ratio (0.518) obtained from a Judd-Ofelt analysis were the highest for the 0.5 mol % of Sm 2 O 3 -doped barium sodium borate glass.…”

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.

“…[13] Meanwhile, the combination of TeO 2 and B 2 O 3 will reduce hygroscopicity, broaden emission peaks, improve quantum yields, and depolymerization will make boro-tellurite glasses a viable candidate for a variety of optical and photonic applications. [14][15][16][17][18][19][20][21][22][23][24][25] Incorporation of alkali metal oxides, viz.

A series of quaternary tellurite‐based glasses (72−x)TeO2 + 25B2O3 + 3K2CO3 + xDy2O3, where (x = 0, 0.5, 1, 1.5, 2, 2.5), are prepared using melt quenching technique. The effect of dopants on structural, physical, optical, and thermal properties of alkali boro‐tellurite glasses are studied using the differential thermal analysis (DTA) technique, UV–vis spectrometer, and photoluminescence technique. The density of as‐prepared samples has been obtained using the conventional Archimedes principle and other physical parameters, viz. molar volume and ion concentration, are also calculated using density. The optical absorption spectra exhibits different excited states of Dy3+ corresponding to 6H15/2→ 6F5/2(∼805 nm), 6F3/2(∼755 nm), 4F9/2 (∼473 nm), 4I15/2 (∼454 nm), 4G11/2 (∼427 nm), 4F7/2(389 nm), 4P3/2(∼366 nm). With the increase in Dy+3 concentration, an increase in optical bandgap, density, and molar volume as well as decrease in molar reflectivity, and reflection loss is evident from this study. The effect of Dy+3 ion concentration on Y/B intensity ratios and CIE chromaticity coordinates have been evaluated to understand the possible applications of aforementioned glass samples for white‐light‐emitting diodes (WLEDs). Moreover, various shielding parameters, viz. half value layer (HVL), mean free path (MFP), effective atomic number (Z eff), mass attenuation coefficient (MAC) have also been determined to understand the shielding characteristics of as‐prepared glass samples.

“…In addition, it has been found to boost glass chemical stability by combining both network formers. Mixed glass formers (MGFs) of alkaline and alkaline such as boro-phosphates [4,5], borosilicates [6,7], and telluro-phosphate [8,9] are thoroughly investigated since the structure of a glass that is formerly used for host-glass is accessible and, according to the study, provides favorable places for cations. Glasses with borosilicate have specific and enhanced qualities, including capacity to transmit UV-NIR, high clarity, mechanical strength, resistance to corrosion, strong chemical stability, high transitional glass temperature and low optical losses in the near and mid-infrared range [10,11].…”

The physical, structural, thermal, and optical properties of heavy metal (Ho3+) oxide incorporated lithium-boro-phosphate glass prepared utilizing melt quenching process are presented in this paper as a function of dopant concentration. To support the findings of the FTIR and DSC studies, many theoretical, experimental, physical, and optical parameters were calculated. XRD and FTIR measurements revealed the prepared glasses’ amorphous nature and the presence of significant borate functional groups. The optical band gap, Urbach energy, and steepness characteristics were tested to validate the structural results. The emission spectrums were recorded in the prepared glasses for an excitation of 450 and 550 nm to find powerful emission color. The color co-ordinates (0.33, 0.41) were found to be quite comparable to white light color co-ordinates. The present glasses can, therefore, be ideal candidates for possible applications with light-emitting diodes.
