“…The increased photoluminescence peak of Er 3+ -borate glasses at 980 nm indicates a high prospect in long-range photoamplification applications (i.e., broadband telecommunication). Further, the improved ferro- and piezoelectric properties of Er 3+ -Li/KNN ceramics , caused by the addition of Er 2 O 3 indicates great potential in multifunctional device applications as well.…”

“…70 The luminescence amplification was observed at 980 nm because of the quenching effect of Er 3+ concentrations. Moreover, the Er 3+ was used as a multifunctional dopant in both (Li,K,Na)NbO 3 (Li-KNN) 3 and (K,Na)NbO 3 123 ceramics. The addition of 0.5% Er 2 O 3 significantly improved the ferro-and piezoelectric properties (i.e., due to the doping impact of the donor) of the ceramic synthesis and resulted in an intense photolumines- cence.…”

“…Some challenges of REO applications are also apparent in display and photoluminescence studies. Although the ferroelectric attribute of Er 3+ -Li/KNN ceramics was enhanced with the addition of Er 2 O 3 , , the surplus amount could demolish the microstructure of the ceramic composites. The photoluminescence peak of Eu 3+ -quaternary glasses can also alter at different wavelengths due to the presence of divalent metal contents (i.e., Ca 2+ , Sr 2+ , Eu 2+ , etc.)…”

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 general, rare earth doped piezoelectric materials can exhibit the photoluminescence properties [5,6], which provides potential use in non-contact optical temperature sensing. According to previous literatures, quite a few efforts have been made in improving their piezoelectricity and luminescence properties of KNN based ceramics by rare earth ions doping [7,8]. Lanthanide doped up-conversion materials can convert two or more low energy photons into a high energy photon, which have several advantages of sharp emission peak, low auto-fluorescence background signal and high resistance to photo bleaching [9].…”

Er3+ doped potassium sodium niobate (KNN: Er) ultrafine powders have been prepared by pulsed laser ablation in water. X-ray diffraction (XRD) pattern of the sample demonstrated that the as-synthesized powders were crystalized in orthorhombic phase. Scanning electron microscopy (SEM) and transmittance electron microscopy (TEM) images exhibited that the morphology of ultrafine powders are cube-like. Under the excitation of 980 nm laser, the sample exhibits green emission, which is originated from the transition of thermal coupled energy levels (2H11/2, 4S3/2) to ground state level 4I15/2. Temperature dependent up-conversion emission intensity associated with thermal quenching of total green emission band and the fluorescence intensity ratio (FIR) between two sub-emission bands related to population of thermal coupled energy levels are investigated for temperature sensing in the temperature range of 300 K to 480 K. The temperature sensing performances related to different technique were discussed. A maximum relative sensitivity reaches 1.01% K-1 at 464 K for emission intensity thermometry and that is 0.84% K-1 at 374 K for FIR thermometry technique. All these results show that KNN: Er ultrafine phosphors prepared via pulsed laser ablation in water have prospect for non-contact temperature sensing.
