“…The molar volume goes up from 25.797 to 27.199 (cm 3 /mol), and the density goes up from 3.635 to 3.690 (g/cm 3 ). The studied glasses became denser due to the replacement of Dy 2 O 3 with a higher molecular mass (372.98 amu) for BaO with a lower molecular [26]. The increase in V m is also linked to the fact that dysprosium atoms are bigger (228 pm) than barium atoms (222 pm).…”

This work aims to investigate the changes in characteristics seen in the composition 60B2O3+ (30-x) BaO+10SiO2 +xDy2O3 where x is 0.0, 1.0, 2.0, and 3.0 mole% glass samples. Melt-quenching technique was used to prepare the glass samples. A variety of analytical techniques were employed to characterize the prepared glasses, such as X-ray, Raman, photoluminescence, and UV-Vis-NIR spectroscopy. XRD spectra verified the glassy nature. The glasses' compactness was studied using structural properties such as density, molar volume, and oxygen packing density. Glass absorption spectra showed eleven distinct peaks in the range 300–2000 nm, resulting from Dy3+ electronic transitions. Urbach energy, refractive index, and optical band gap energy were determined. The optical parameters, such as molar refraction, molar polarizability, reflection loss, optical transmission, metallization, and optical electronegativity, were estimated. The photoluminescence spectra revealed five distinct peaks in the 400–750 nm wavelength range under excitation at 325 nm. Makishima-Mackenzie's (M-M) method was used to determine mechanical parameters such as elastic moduli, Poisson's ratio, and hardness, and it was found that these properties decreased with increasing Dy2O3 concentration.

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.

“…In recent years, rare earth doped luminescent materials have been widely researched and applied in the fields of LED lighting, dynamic display, laser remote sensing, and bioprobes [1][2][3][4][5][6] because of their good luminescence properties, high interference resistance, and high stability. Different kinds of substrates such as oxides, 7 sulfur oxides, 8 fluorides 9,10 and phosphates 11,12 can greatly affect the luminescence performance of the materials, so the matrices have attracted more researchers' attention.…”
