This paper reports the first fluorescent sensor that can simultaneously detect multiple rare earth metal ions (Y 3+ , Yb 3+ , Sc 3+ and Ce 3+ ) in a variety of rare earth metal ions. The Schiff base TPE-A was synthesized in 85% yield by the condensation reaction of formyltetrastyrene with 4-aminoantipyrine. Long wavelength fluorescence of TPE-A was observed at 500–650 nm in both MeOH and MeCN solutions. In methanol, it showed a highly selective response to Y 3+ with a fluorescence color change from red to yellow-green, while it exhibited fluorescence quenching for Yb 3+ . Additionally, it exhibited a selective sensing ability for Sc 3+ in MeCN solution with a fluorescence color change from red to yellow, and a fluorescence quenching effect for Ce 3+ . In addition, it can detect these four rare earth metal ions simultaneously by fluorescence changes with the assistance of EDTA-2Na. It can be used as a fluorescence sensor for MeOH (Y 3+ and Yb 3+ ) and MeCN (Sc 3+ and Ce 3+ ), respectively. The ICT effect of the TPE-A probe on Y 3+ was investigated using femtosecond transient absorption spectroscopy and quantum chemical calculations. The detection limits of Y 3+ , Yb 3+ , Sc 3+ and Ce 3+ were 1.6 × 10 −8 mol/L, 1.04 × 10 −7 mol/L, 8.35 × 10 −8 mol/L and 1.31 × 10 −8 mol/L, respectively, as deduced from Job's plots, spectral titrations, and ESI-MS. And the detection of measured water in MeCN was realized by TPE-A-Sc 3+ hybrid system. This implies an efficient and simple method for the simultaneous analysis of trace rare earth metal elements (Y 3+ , Yb 3+ , Sc 3+ and Ce 3+ ) in complex environments.

Yb 2 WO 6 : Er 3+ , Y 3+ phosphors were successfully synthesized using the high-temperature solid-state method. • Y 3+ doping significantly enhances the upconversion luminescence intensity of Yb 2 WO 6 : Er 3+ phosphor. • The red and green emission intensities are increased by 2.17 and 2.20 times. • The maximum of relative sensitivity and absolute sensitivity is 6.97%·K⁻¹ at 450 K and 1.90%·K −1 at 523 K, respectively. Er 3+ and Y 3+ ions co-doped Yb 2 WO 6 phosphors were synthesized via a high-temperature solid-state method. Under 980 nm excitation, the Y 3+ -substituted Yb 2 WO 6 :Er 3+ phosphors exhibit green emission near 545 nm and red emission near 657 nm, assigned to the Er 3+ 4 S 3/2 → 4 I 15/2 and 4 F 9/2 → 4 I 15/2 transitions, respectively. At the optimum Y 3+ content of x = 0.20, the red and green emission intensities are 2.17 and 2.20 times those of the Y 3+ -free sample, respectively. Yb 3+ ions act as the primary sensitizers by absorbing 980 nm photons and transferring energy to Er 3+ . Sequential Yb 3+ →Er 3+ energy-transfer steps, together with phonon-assisted relaxation among Er 3+ levels, populate the 4 S 3/2 and 4 F 9/2 emitting states. The enhanced upconversion emission and the measured temperature-dependent fluorescence-intensity ratio indicate that the phosphor is a potential candidate for non-contact optical thermometry over 298–523 K. S R reaches its maximum value of 6.97%·K −1 at 450 K. while S A attains its maximum of 1.90%·K −1 at 523 K. Download: Download high-res image (167KB) Download: Download full-size image

Developing functional separators capable of simultaneously suppressing lithium dendrite growth and enabling compatibility with high-voltage cathodes is critical for realizing long-cycle-life lithium metal batteries. Herein, a synergistic bulk–interface regulation strategy is achieved via a coatable Y3+/Zn2+ codoped LATP/PVDF-HFP composite coating applied onto a commercial polypropylene (PP) separator. Y3+/Zn2+ codoped Li1.3Al0.275Y0.025Ti1.7(PO4)3 (LAYTP-Zn) is synthesized via a solid-state route and uniformly integrated with PVDF-HFP to form a conformal coating with strong interfacial adhesion. Y3+/Zn2+ incorporation induces lattice expansion of LATP, thereby broadening bulk Li+ transport pathways. In addition, Zn2+ regulates interfacial chemistry by enhancing electrolyte dissociation and anchoring anions through Lewis acid interactions, while also promoting the formation of polar β-phase PVDF-HFP, collectively increasing the Li+ transference number to 0.79. In addition, the polymer matrix serves as a physical barrier that mitigates direct interfacial side reactions. The coordinated regulation of bulk ion conduction and interfacial ion distribution enables a more uniform Li+ flux and facilitates the formation of a LiF-enriched and mechanically robust interphase, thereby suppressing dendrite nucleation and growth. As a result, Li||Li symmetric cells exhibit stable cycling for over 3000 h at 1 mA·cm–2 and 1 mAh·cm–2. Furthermore, Li||LFP and Li||NCM811 half-cells deliver capacity retentions of 91.2% after 800 cycles at 1 C and 95.1% after 200 cycles at 0.5 C, respectively, while maintaining stable operation up to 4.73 V. This work provides a scalable separator design that integrates bulk transport optimization with interfacial regulation, offering a practical pathway toward high-performance lithium metal batteries.

A series of SrF 2 phosphors co-doped with Er 3+ and Y 3+ possessing regular polygon shapes were fabricated after calcination as-synthesized particles at 600 °C for 2 h. the crystal structure and morphology of the Er, Y:SrF 2 phosphors were identified. By incorporating the non-active Y 3+ ions as buffers into Er:SrF 2 phosphors, intense green up-conversion luminescence with modulating emission colors from reddish-yellow towards the greenish area is achieved. The two-photon up-conversion mechanism was also identified by the quadratic dependence between the luminescence intensities and 808 nm excitation source powers. The up-conversion luminescence characteristics indicate that Y 3+ buffers significantly enhance the 2 H 11/2 / 4 S 3/2 → 4 I 15/2 transitions, leading to an approximately five-fold increase in the luminescence intensities ratio R(g/r) of the green to red emissions in Er:SrF 2 phosphors.

A new sol-gel method that employs cation exchange from an aqueous metal ion solution with H+ions of granulated alginic acid was developed for synthesizing high-purity Y2O3nanoparticles. In this study, the cation exchange kinetics of H+~Y3+in aqueous solution were analyzed using on-line pH technology and off-line inductively coupled plasma-atomic emission spectrometry (ICP-AES) analysis. Pseudo 2nd-order models were utilized to evaluate the parameters of the kinetics, suggesting that the concentration of H+~Y3+involved in the cation exchange reaction was 1:1.733. Further, a comprehensive understanding of the Y-ALG calcination process was developed using thermo-gravimetric analysis, along with results obtained from differential scanning calorimetry (TGA/DSC). A detailed analysis of the XRD Rietveld refinement plots revealed that the crystallite sizes of Y2O3nanoparticles were about 4 nm (500 °C) and 15 nm (800 °C), respectively. Differential pulse voltammetry (DPV) was employed to investigate the electrochemical oxidation of catechol. The oxidation peak currents of catechol at Y2O3(500 °C)/GCE and Y2O3(800 °C)/GCE showed two stages linear function of concentration (2.0~20.0 × 10−6mol/L, 20.0~60.0 × 10−6mol/L). The results indicated that the detection limits were equal to 2.4 × 10−7mol/L (Y2O3(500 °C)/GCE) and 7.8 × 10−7mol/L (Y2O3(800 °C)/GCE). The study not only provided a method to synthesize metal oxide, but also proposed a promising on-line pH model to study cation exchange kinetics.

Temperature-sensitive materials are increasingly of deep interest to researchers. Ion imprinting technology is widely used in the field of metal recovery. In order to solve the problem of rare earth metal recovery, we designed a temperature-sensitive dual-imprinted hydrogel adsorption product (CDIH) with chitosan as the matrix, N-isopropylacrylamide as a thermally responsive monomer , and La 3+ and Y 3+ as the co-templates. The reversible thermal sensitivity and ion-imprinted structure were determined by differential scanning calorimetry , Fourier transform infrared spectrometer, Raman spectra , Thermogravimetric analysis , X-ray photoelectron spectroscopy , Scanning electron microscopy and X-ray energy spectroscopy various characterizations and analyses. The simultaneous adsorption amount of CDIH for La 3+ and Y 3+ was 87.04 mg/g and 90.70 mg/g, respectively. The quasi-secondary kinetic model and Freundlich isotherms model well described the adsorption mechanism of CDIH. It's worthy to mention that CDIH could be well regenerated through washing with deionized water at 20 °C, with a desorption rate of 95.29 % for La 3+ and 96.03 % for Y 3+ . And after 10 cycles of reuse, 70 % of the adsorption amount could be maintained, revealing excellent reusability. Furthermore, CDIH expressed better adsorption selectivity to La 3+ and Y 3+ than its non-imprinted counterparts in a solution containing six metal ions .

With the increasing global climate change, ochratoxin A (OTA) pollution in food and environment has become a serious and potential risk element threatening food safety and human health. Biodegradation of mycotoxin is an eco-friendly and efficient control strategy. Still, research works are warranted to develop low-cost, efficient, and sustainable approaches to enhance the mycotoxin degradation efficiency of microorganisms . In this study, the activities of N-acetyl- L -cysteine (NAC) against OTA toxicity were evidenced, and its positive effects on the OTA degradation efficiency of antagonistic yeast, Cryptococcus podzolicus Y3 were verified. Co-culturing C. podzolicus Y3 with 10 mM NAC improved 100% and 92.6% OTA degradation rate into ochratoxin α (OTα) at 1 d and 2 d. The excellent promotion role of NAC on OTA degradation was observed even at low temperatures and alkaline conditions. C. podzolicus Y3 treated with OTA or OTA+NAC promoted reduced glutathione (GSH) accumulation. GSS and GSR genes were highly expressed after OTA and OTA+NAC treatment, contributing to GSH accumulation. In the early stages of NAC treatment, yeast viability and cell membrane were reduced, but the antioxidant property of NAC prevented lipid peroxidation. Our finding provides a sustainable and efficient new strategy to improve mycotoxin degradation by antagonistic yeasts, which could be applied to mycotoxin clearance.

Rare earth ion-doped perovskite oxide phosphors are crucial for white light-emitting diode devices. In this study, high-performance red phosphors SrIn 1.95- x O 4 :0.05Eu 3+ , x Y 3+ (SIO:0.05Eu 3+ , x Y 3+ , 0 ≤ x ≤ 0.3) and SrY 1- x InO 4 : x Eu 3+ (SYIO: x Eu 3+ , 0 ≤ x ≤ 0.3) were synthesized using high-temperature solid-phase method. The energy bandgap of the new host material, SrYInO 4 is larger than that of SrIn 2 O 4 . The synthesized series of red phosphors exhibit good crystallinity and electronic structure. Under 308 nm excitation, SIO:0.05Eu 3+ ,0.1Y 3+ and SYIO:0.2Eu 3+ show the highest luminescence intensity within their respective series, emitting red light at around 616 nm. Their luminescence intensity is 2.2 times and 4 times higher than the previously reported SrIn 1.95 O 4 :0.05Eu 3+ red phosphors, respectively. Additionally, SIO:0.05Eu 3+ ,0.1Y 3+ , and SYIO:0.2Eu 3+ display high color purity (87.1 % and 96.5 %, respectively), microsecond level fluorescence lifetime and excellent thermal stability. SIO:0.05Eu 3+ ,0.1Y 3+ , and SYIO:0.2Eu 3+ show significant potential for application as red-emitting components in WLED devices.

Er, Y:SrF 2 particles co-doped with various Y 3+ buffer ions were prepared after calcined as-synthesized particles at 600 °C, and the residual nitrates and –OH disappear drastically after calcination treatment. XRD and FE-SEM measurements were proposed to identify the crystal structures and morphologies of the Er, Y:SrF 2 particles, respectively. The emission spectra illustrated two distinct emission bands, which can be attributed to the 2 H 11/2 / 4 S 3/2 → 4 I 15/2 and 4 F 9/2 → 4 I 15/2 transitions of Er 3+ ions, respectively. The dependence of green to red emission intensity ratio R(g/r) and the decay curves on the Y 3+ buffer ions co-doping contents were investigated to elucidate the emission mechanisms. It was observed that the 2 H 11/2 / 4 S 3/2 → 4 I 15/2 transitions were enhanced relative to 4 F 9/2 → 4 I 15/2 red-emitting transition under 488 nm and 980 nm excitation in high-symmetry Er, Y:SrF 2 particles after co-doped with Y 3+ buffer ions.

Recovery of rare earth metal is a global concern for resource-efficient application and high-tech industry development. In this study, a new Y 3+ adsorbent, namely chitosan-based Y 3+ -imprinted hydrogel with reversible thermo-responsibility (CYIT) was synthesized, using Y 3+ as the template ion. The obtained CYIT was comprehensively characterized by means of DSC, FTIR, LRS, TGA, SEM, and XPS. As revealed from the results, CYIT possesses stable reversible thermo-responsibility confirmed by the phase transition temperature ranging from 29.2 °C to 38.4 °C. Its maximum adsorption capacity on Y 3+ is up to 160.0 mg/g, much higher than the corresponding performance of similar hydrogels. More significantly, this type of adsorbent could be effectively regenerated by simply leaching with cold water and the desorption efficiency reached 96.2 % after wash by cold water at 15 °C for 25 min. Besides, the remarkable reusability should also be highlighted, for the adsorption capacity and desorption efficiency remained as 124.8 mg/g and 90.0 %, respectively, after five adsorption–desorption cycles. In the coexistence of other interfering metal ions (including La 3+ , Gd 3+ , Cu 2+ , Al 3+ , and Fe 3+ ), CYIT also exhibited better adsorption selectivity than the corresponding adsorbent without Y 3+ -imprinting.

A ratiometric fluorescence probe is proposed for sensitive and visual detection of tetracyclinee (TC) based on cascade fluorescence signal amplification induced by bovine serum albumin–stabilized copper nanoclusters (BSA-CuNCs) and yttrium ions (Y 3+ ). TC can combine with Y 3+ to form the complex (TC-Y 3+ ) to enhance the fluorescence of TC at 515 nm. Then, positively charged TC-Y 3+ and negatively charged BSA-CuNCs was bonded together by electrostatic interactions to achieve the fluorescence resonance energy transfer (FRET) process. With the increase of TC concentration, the fluorescence intensity of TC-Y 3+ at 515 nm (F 515 ) gradually increased; meanwhile, the fluorescence intensity of BSA-CuNCs at 405 nm (F 405 ) decreased gradually. The ratio of F 515 and F 405 was used for the quantitative determination of TC. The linear range of the constructed fluorescent probe is 1.0 to 60.0 μM, and the limit of detection is 0.22 μM. The method was successfully applied to the determination of TC in spiked milk with recoveries ranging from 94.3 to 112%. Furthermore, the color of this platform can be observed from dark violet to bright green under the UV lamp. Since the response time of the reaction is less than 10 s, an intelligent sensing platform based on the use of the smartphone as image acquisition equipment was also established to realize rapid on-site and portable detection of TC through the colorimetric recognition application.

Despite the excellent mechanical properties of SiC f /SiC composites, the extremely harsh corrosion limits their durability as structural materials for high-temperature applications. Here, we propose a synergistic Al 3+ /Y 3+ stabilization strategy to achieve highly durable SiC f /SiC composites with enhanced mechanical stability. This is realized by constructing an Al/Y co-diffused SiC matrix, which can form a robust YAlSi x O y glass network under high-temperature atmospheric (40% H 2 O & 60% O 2 ) corrosion. The Al/Y co-diffused SiC f /SiC composites (SiC f /SiC-Al40Y) exhibit high bending strength retention of 98.5% after corrosion at 1200 ℃, as well as 78.9% up to 1300 ℃, significantly exceeding those of the counterparts without diffusion treatment. The improved mechanical stability is primarily attributed to the synergistic Al 3+ /Y 3+ stabilization of corrosion-induced SiO 2 glass network, which can suppress the matrix cracking and thus mitigate the corrosion. This work demonstrates the strategy of synergistic Al 3+ /Y 3+ stabilization for constructing SiC f /SiC composites with enhanced durability, offering an innovative concept to develop SiC f /SiC composites applicable at higher temperatures for thermo-structural applications.
