“…The optical absorption spectra of GO coated TNd (NPs) glasses were presented in Figure 6. XRD analysis revealed that the absorption spectra edges in glass samples are not strongly defined, indicating a non-crystalline/amorphous structure [18]- [20]. There are several peaks that emerge from the ground state ( 4 I 9/2 ) to the excited state.…”

“…Moreover, the increasing trend of optical basicity may be due to ZnO which has a higher basicity value (0.82) than borate oxide (1.75) [32]. According to Azlan et al, [33], an increase in optical basicity indicates an increase in the ability of oxide ions to donate electrons to the surrounding cation. Additionally, as the polarizability of oxide ions increases, the optical basicity of the glass system increases [30].…”

The versatility of graphene oxide (GO) as coating materials on the glass surface is a new revolution in the advanced glass era. In this work, GO liquid solution was prepared by using electrochemical exfoliation in an electrolyte solution assisted by different surfactants. Meanwhile, a glass series was prepared by using the conventional meltquenched technique. A low-cost and simple spray deposition technique was used to deposit the GO on the glass sample. The obtained glass series was denoted as GO coated TNd (NPs), meanwhile, the uncoated glass was labelled as uncoated TNd (NPs). The linear optical properties of GO coated TNd (NPs) glass series was determined using UVVis spectrophotometer and utilizing the Lorentz-Lorentz equation to determine the value of polarizability. X-ray diffraction spectra revealed the amorphous structural characteristics of the glass series. The SEM morphological image revealed the variation of GO distribution on the glass surface due to the agglomeration and inhomogeneity of GO distribution on the glass surface. The homogeneity of GO distribution on the glass surface is negligible in this work as we focus solely on the effect of GO on glass properties. According to the observations, the value of GO-coated TNd (NPs) is in the range 3.4531- 3.8549 Å and uncoated TNd (NPs) is in the range 2.709- 2.774 Å. Meanwhile, the optical basicity value ranges from 1.220 to 1.262. These results demonstrate that the polarizability of oxide ions and optical basicity values of the GO coated TNd (NPs) glass series was higher than the uncoated TNd (NPs) glass. The metallization criterion for the GO-coated TNd (NPs) glass system is in the range of 0.3 < M < 0.4. Based on these results, the obtained glasses are promising in linear optical glass fibre.

“…The introduction of Er 3+ impurities led to an increased density and improved spectroscopic properties of the Er 3+ -TiO 2 barium glass and can be useful for optical applications. The density and refractive index were greater for the Er 2 O 3 nanoparticles-zinc borotellurite glass compared to its original counterpart, suggesting a potential for nanophotonic applications. Moreover, the potent photocatalytic activity (both in duration and magnitude) of Er 2 O 3 -silica also highlights the potential in thermal imaging for a clinical diagnosis.…”

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.

“…From 2018 to 2022 gammaray and neutron shielding features of tellurite glasses were achieved to be used in nuclear shielding areas [4]. Besides that, borotellurite glass systems doped with erbium and erbium nanoparticles have been achieved and glasses with erbium nanoparticles got a higher refractive index to be a candidate for photonic applications [5]. Moreover, in 2022, Tm 3+ /Er 3+ /Sm 3+ tri-doped TeO2-Li2O-ZnO glasses have been achieved for temperature sensors using color emissions and for generating white light sources were investigated and these glasses are promising platforms for optical temperature sensing [6].…”

Theoretical analysis of room temperature bulk modulus and low-temperature ultrasonic attenuation coefficient in the glass system (1-x)TeO2-xV2O5, x = 20, 25, 30, 35, 40 mol % was achieved. The bond compression (BC) and Makishima-Mackenzie (MM) models were used to interpret room-temperature bulk modulus K. The main parameters used were: average cross-link density, number of network bonds per unit volume, and average atomic ring size (). Analyses of low-temperature (300 − 150 K) ultrasonic attenuation (α) at 2, 4, 5, and 6 MHz were achieved by calculating: potential energy, centers of energy loss, elongation, and contraction of the two-well potential. Also, the deformation potential is found to be sensitive to the variations of the modifier content. The analysis revealed a sensitive effect of variation of modifier contents for elongation or contraction of the dual-well potential. The number of centers of energy loss is related to the elastic moduli as a function of the modifier content. Correlation between room temperature bulk modulus and ultrasonic attenuation coefficient has been achieved.
