“…Silver 3d 5/2 and 3d 3/2 photoelectron peaks could be observed at 368.1 eV and 374.1 eV respectively. Separation distance of 6 eV between two components is characteristic for silver in metallic form 52 , 53 . Additionally, to confirm metallic state of silver, the Auger parameter (α) has been calculated according to the formula: where BE is the binding energy of Ag3d 5/2 peak and KE is the kinetic energy of Ag M 4 N 45 N 45 ) peak 52 , 54 , 55 .…”

Formation of plasmonically active silver, copper and composite silver-copper nanostructures were studied in this paper. Metallic nanostructures were fabricated by thermal disintegration, so called dewetting, of the thin films in an argon atmosphere. The formation process of the nanostructures was in-situ observed by a novel method, based on resistance measurements. The influence of the material and thickness of the initial thin film on temperature of their disintegration was investigated. Electrical measurements were validated by scanning electron microscopy observations, while metallic the behavior of nanostructures was studied by XPS method. The formation of silver-copper nanocomposite structures was confirmed by UV–vis spectroscopy. Plasmon resonance with two characteristic peaks for nanocomposite structures was observed.

“…The unaltered lifetime and combined emission will be useful to achieve smart lighting like the circadian light cycle. The simultaneous emission of Dy 3+ and Eu 3+ (at 390 nm) was evident from Dy 3+ /Eu 3+ tellurite glass materials . The emission color was hinged on the Dy/Eu ratio; hence, it is suitable for fabricating color-tunable phosphors.…”

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.

“…There are a few strategies looked by specialist, for example, sol-gel [5], ignition [6], solid state reaction [7], and co-precipitation [8], to effectively manufacture phosphor materials. In examination with different strategies, the combustion rule gives a few bene ts, for example, great stoichiometric control, high homogeneity, accommodation, cost viability, little and uniform molecule size and the capacity to create nanostructure powders [9][10].…”

Magnesium aluminates-based nanophosphors have been synthesized using the combustion reaction, where Nd3+ were varied from 0 to 0.075 molar concentrations. SrMgAl12O19:Nd3+ was studied for its morphology, structure, and photoluminescence properties. The XRD patterns from all samples were well correlated with the standard XRD pattern of SrAl12O19 (JCPDS File No. 89-2505). A study using energy dispersive X-ray spectroscopy (EDS) demonstrated the presence of all the expected elements in the configuration.A scanning electron microscopy study revealed that the surfacemorphologychanged as the concentration of Nd3+ increased. PL Spectroscopic measurements of Nd3+ ions at 475 (cyan) and 575 (yellow) nm have been made by directly exciting them at 350 nm, corresponding to 4D3/2 + 4D5/2,2P1/2, → 4F3/2 transitions, respectively. Results from color coordinates provided by the (CIE 1931) indicate that the cyan blue emission color originates from the synthesized phosphor.
