Lithium–sulfur (Li–S) batteries are considered as very promising energy storage systems due to their higher theoretical performance and lower active material cost. However, the notorious shuttle effect and lithium dendrite growth have severely restricted the industrial production of Li–S batteries. In this study, we used polyethylene oxide (PEO) as the matrix and added multifunctional nanofillers (nano In 2 O 3 ) to effectively inhibit the shuttle effect caused by the dissolution of lithium polysulphides (LiPSs) in Li–S batteries. As a multifunctional filler, nano-In 2 O 3 not only improves the ionic conductivity of the PEO electrolyte, but also forms a Li–In alloy layer in situ at the polymer/anode interface, which can cause the rapid diffusion of lithium ions and prevent the side reactions between lithium metal anode and the electrolyte. Achieving the effect of stabilizing the lithium metal anode and suppressing the shuttle effect. Multiple problems in the system are solved by introducing a single component with multiple functions. The symmetrical lithium battery based on the PEO/LiTFSI/In 2 O 3 solid polymer electrolyte (PEO/LiTFSI/In 2 O 3 SPE) has higher cycle stability (over 1200 h) because it is more stable to the lithium metal anode. The Li–S full battery also exhibits excellent electrochemical performance. After 500 cycles at 1C, its capacity can be maintained at 570 mAh g −1 , the capacity decay rate is 0.038%. The coulombic efficiency (CE) during the cycle is also close 100%.

In-doped NZSP solid electrolytes were prepared via a modified solid-state reaction method. • The doping of In induces a monoclinic-to -rhombohedral phase transition. • In doping promotes the growth of grains, resulting in grain boundary reduction. • The Na 3.3 Zr 1.7 In 0.3 Si 2 PO 12 electrolyte shows the highest ionic conductivity of 1.24 mS/cm. NASICON-type Na 3 Zr 2 Si 2 PO 12 (NZSP) solid electrolytes are promising candidates for solid-state sodium-ion batteries (SSSIBs) owing to their high ionic conductivity, and excellent air stability. In this study, Na 3+x Zr 2-x In x Si 2 PO 12 (x = 0, 0.1, 0.2, 0.3, and 0.4) solid electrolytes were synthesized using a modified solid-state reaction method, and the effect of the In dopant content on the structure and properties of the NZSP electrolytes was investigated by XRD, SEM, and EIS. The introduction of In induces a monoclinic-to -rhombohedral phase transition. The rhombohedral phase has a large unit cell volume, which provides bigger channels for the conduction of Na ions. Moreover, In doping also promotes the growth of grains within the electrolyte, resulting in grain boundary reduction. The Na 3.3 Zr 1.7 In 0.3 Si 2 PO 12 electrolyte exhibits the highest ionic conductivity of 1.24 mS/cm at 30 °C, the lowest activation energy of 0.345 eV, and a negligible electronic conductivity of 1.81 × 10 −8 S/cm. A Na/Na 3.3 Zr 1.7 In 0.3 Si 2 PO 12 /Na symmetric cell shows an excellent cycling stability. These results demonstrate the good promise of Na 3.3 Zr 1.7 In 0.3 Si 2 PO 12 material as an alternative solid electrolyte for SSSIBs.

Anisotropic two-dimensional (2D) materials with low structural symmetry and in-plane optical anisotropy provide a promising platform for the development of polarization-driven photonic devices. Herein, high-quality subcentimetre-scale InTeO3Cl single crystals were prepared using the chemical vapor transport (CVT) method and further exfoliated to flakes of nanometer thickness. The crystal structure, optical anisotropy, bandgap, and stability of 2D InTeO3Cl were extensively investigated. Raman characterization verified the strong in-plane optical anisotropy of 2D InTeO3Cl. Furthermore, it presented an optical bandgap of 2.6 eV and excellent environmental and thermal stability. Interestingly, 2D InTeO3Cl manifested an anisotropic second-harmonic generation (SHG) response, which originated from a centrosymmetry breaking induced by periodic interlayer dislocation. Our work reveals the outstanding in-plane optical anisotropy and nonlinear optical effects of 2D InTeO3Cl and provides a promising candidate for the development of high-performance optical and photonic devices.

Far-red phosphors featuring high quantum efficiency and emission bands that strongly overlap with the absorption spectra of plant pigments are crucial for advancing plant cultivation lighting technology. Restricted by the large Stokes shift, far-red phosphors typically exhibit low energy efficiency. Moreover, many far-red phosphors suffer from low quantum efficiency, which has emerged as a critical issue in the research of these materials. To address the issue, conventional strategies—including crystal field engineering, defect engineering, and sensitizer doping—have been widely adopted to enhance their emission intensity. In this work, we propose a novel and effective strategy to improve the emission performance of far-red phosphors: low-melting-point magnesium chloride has been introduced as a flux to regulate the reaction pathway of the composite oxide phosphor Ca14Mg5.94Li0.03In0.03Ga9.95O35:0.05Mn4+(CMLIGO:0.05Mn4+). The cubic intermediate product with a structure analogous to the target product has been designed to form a compact lattice structure and reduce crystal defects, thereby enhancing the luminescence intensity and quantum efficiency of the phosphor. The Ca14Mg5.94Li0.03In0.03Ga9.95O35:0.05Mn4+@3 wt% MgCl2(CMLIGO:0.05Mn4+@3 wt% MgCl2) shows a broad excitation band (250–600 nm) and far-red emission centered at 720 nm (650–800 nm). Under 365 nm excitation, the CMLIGO:0.05Mn4+@3 wt% MgCl2exhibits an internal quantum efficiency of 91.4%. Benefiting from its high internal quantum efficiency and the emission band that matches well with the absorption spectrum of phytochrome in the far-red absorbing form (phytochrome Pfr), CMLIGO:0.05Mn4+@3 wt% MgCl2demonstrates promising potential for applications in plant cultivation lighting. This work offers a new direction for synthesizing and modification of composite oxide phosphors.

Broadband near-infrared phosphors with longer wavelengths are urgently needed for applications such as deep-tissue biomedical imaging. However, the detailed mechanism of Mn 2+ -activated NIR emission remains elusive. Guided by the theory of the nephelauxetic effect, sulfide phosphors with strong covalent bonding have become among the most promising alternatives for obtaining Mn 2+ long-wavelength luminescence. On this basis, the synergistic strategy of combining stronger crystal field effects can make the red-shift emission of isolated Mn 2+ more reliable. In this work, we studied a series of M(Ga, In) 2 S 4 :Mn 2+ (M = Ca, Sr, Ba) phosphors featuring strong crystal field environments, and reported for the first time the luminescence behaviors of Mn 2+ -doped MIn 2 S 4 :Mn 2+ (M = Sr, Ba). The preferential occupation behavior of different sites results in significant differences between MGa 2 S 4 :Mn 2+ (M = Ca, Sr) and MIn 2 S 4 :Mn 2+ (M = Sr, Ba) with the same crystal structure. The severe distortion of the polyhedra further enhances their performance in ultrawideband deep red to near-infrared luminescence (600–850 nm, FWHM ≈ 123–257 nm), which is far superior to that of similar materials. Furthermore, the fabricated PC-LED devices have excellent vascular imaging and plant illumination capabilities. This study provides a new perspective for understanding the near-infrared luminescence of Mn 2+ .

High-entropy engineering has emerged as a transformative strategy to enhance the functional properties of ceramic materials. In this study, we synthesized and systematically evaluated high-entropy TiO 2 -based ceramics, [Ta 0.5 (In 0.2 Tm 0.2 Gd 0.2 Ga 0.2 La 0.2 ) 0.5 ] x Ti 1‒ x O 2 ( x = 0.5%, 1%, 2%, 3%), incorporating multiple donor‒acceptor cation pairs to achieve synergistic improvements. The optimized composition exhibited an extraordinary dielectric constant of ∼2.7 × 10 4 , ultra-low dielectric loss of 0.007 at 1 kHz, and exceptional thermal stability across a wide temperature range. These outstanding properties are attributed to the interplay of internal barrier layer capacitance and electron-pinned defect dipole effects. Additionally, high-entropy engineering introduced significant lattice distortions, resulting in a 109% increase in Vickers hardness compared to undoped TiO 2 . First-principle calculations demonstrate that high-entropy doping with trivalent–pentavalent ion pairs in rutile TiO 2 stabilizes multiple defect configurations. This work highlights the potential of high-entropy engineering as a robust tool for advancing TiO 2 -based dielectric ceramics, while establishing a solid foundation for material innovations.

Expanding plasmonic catalysis from noble metals to earth-abundant oxides is important for sustainable solar-to-chemical conversion, but mechanisms remain poorly understood. Here, we show that lithium-reduction-induced defects modulate the electronic structure of indium oxide, increasing free-carrier concentration 2.5-fold and producing a near-infrared plasmon-like response. Computational and spectroscopic analyses suggest that oxygen vacancies act as preferential hot-electron traps, enhance near fields, and shift the kinetically sensitive step from methoxy dehydrogenation on pristine surfaces to intermediate dehydrogenation on defective surfaces. Injection of plasmon-induced hot electrons into intermediate antibonding orbitals may reduce the apparent activation energy from 75.7 to 27.8 kJ mol −1 . In this work, we report a competitive methanol steam reforming catalyst with a hydrogen production rate of 214 μmol gcat −1 s −1 and show how defect and electronic engineering can tailor oxide-based plasmonic systems.

A series of new phosphors, Sm 3+ -doped InGaZnO 4 (IGZO:Sm 3+ ), was synthesized using a high-temperature solid-state reaction method. The structures of IGZO:Sm 3+ samples belong to the R \(\overline{3 }\) m space group (No. 166). The excitation spectrum of IGZO:Sm 3+ showed an optimal excitation wavelength at 468 nm. Four distinct peaks were observed in the emission spectrum, with the most prominent peak appearing at 612 nm, corresponding to the 4 G 5/2 – 6 H 7/2 radiative transition of Sm 3+ ions. For effective optical performance, different doping levels were tested, and it was found that the composition IGZO:2 mol% Sm 3+ is the optimal one. The concentration quenching effect is caused by nearest neighbor ion interactions. In the temperature range of 300 to 480 K, the IGZO:Sm 3+ phosphor showed excellent thermal stability which is verified through luminous intensity behavior and the changes in Commission Internationale de l’Eclairage (CIE) chromaticity coordinates. The activation energy ( E a ) for IGZO:Sm 3+ was calculated to be 0.40 eV. Through powder dusting method, latent fingerprint (LFP) information can be deciphered at Level I–III feature. The optical properties, thermal stability and potential application in latent fingerprint development of IGZO:Sm 3 ⁺ were systematically investigated, which provides a new choice of materials and research ideas in related fields.

Lanthanide-doped double perovskites have emerged as promising candidates for remote optical thermometry owing to their pronounced thermally quenched photoluminescence. However, substantial emission attenuation at elevated temperatures poses a challenge to achieving high measurement precision. Herein, a facile solid-state synthesis of efficient lanthanide-doped fluoride double perovskites Cs 2 NaYF 6 , is reported presenting robust anti-thermal quenching behavior while maintaining enhanced thermal sensitivity through partial substitution of Na + with Li + . Li + doping induces lattice contraction and increased stiffness, reducing phonon energy and suppressing electron–phonon coupling, thereby enhancing emission intensity and mitigating the thermal quenching of Er 3+ . Meanwhile, Li + -induced local symmetry distortion around Er 3+ leads to further Stark splitting of 2 H 11/2 , promoting the thermally assisted population of green-emitting levels, which retain 84% of their initial intensity at 523 K. In contrast, the red emission remains unaffected due to the large energy gap between adjacent levels. Consequently, both thermally coupled and non-thermally coupled thermometric sensitivity are enhanced, with a maximum improvement of up to 6-fold, leading to a substantial reduction in temperature uncertainty at high temperatures. Furthermore, the practical applicability of flexible polydimethylsiloxane-based optical fiber and thin-film temperature sensors is demonstrated. This provides insights into simultaneously optimizing the intensity and sensitivity of luminescent thermometers.

Y-doped BaZrO 3 has emerged as a promising ceramic material for hydrogen separation membranes. The conductivity of Y-BaZrO 3 (BZY) ceramics is highly dependent on the concentration of oxygen vacancies. In this work, BZY further individually doped with In and Pr were prepared by the citrate sol–gel combustion method. Effects of doping on the ceramic phase structure, oxygen vacancies, and micromorphology were investigated using a range of analytical techniques, including XRD, Raman spectroscopy, XPS, and SEM. The conductivity, hydrogen permeability, and stability of BaZr 0.7 Y 0.2 In 0.1 O 3−δ (BZYI) and BaZr 0.7 Y 0.2 Pr 0.1 O 3−δ (BZYP) ceramics were systematically evaluated. Upon doping, BZYI exhibits the most favorable conductivity, reaching 9.98 × 10 −3 S·cm −1 in dry air at 800 °C. At 900 °C, with water vapor introduced on the sweep side, the hydrogen permeation fluxes of BZYI and BZYP are 3.50 × 10 −9 mol·cm −2 ·s −1 and 2.60 × 10 −9 mol·cm −2 ·s −1 , respectively. Both samples were exposed to boiling water and a 100% CO 2 atmosphere at 900 °C for 3 h. Post-treatment XRD, Raman, and SEM analyses reveal no formation of heterophase, indicating excellent phase and microstructural stability.

Optical manometry provides noncontact pressure sensing but remains vulnerable to temperature-induced drift, where thermal expansion and nonradiative relaxation distort luminescence spectra and kinetics. We develop a spectro-temporal ratiometric approach that combines spectral and time-gated luminescence channels to decouple pressure and temperature responses and realize thermally invariant optical manometry. Using Y 3 In 2 Ga 3 O 12 :Cr 3+ as a rigid-lattice host (D q/B ≈ 2.2), lattice stiffness minimizes thermal sensitivity S R,T , while ratiometric detection stabilizes pressure sensitivity S R,p . The resulting thermal-invariance manometric factor ( TIMF) = S R,p / S R,T reaches ≈7700 K·GPa −1 in the spectral domain and ≈2500 K·GPa −1 in the time-gated domain, with S R,p up to 51%·GPa −1 . These values exceed ruby benchmarks by two orders of magnitude and surpass conventional lifetime analysis by ∼40 times, enabling accurate, self-referenced optical pressure mapping under extreme thermo-mechanical conditions. This work provides luminescent manometry from empirical calibration to a quantitative framework for thermally reliable sensing in coupled fields.

The high-entropy concept has emerged as a promising strategy for designing ferroelectric ceramics with superior piezoelectric properties. To clarify the role of equal-valence B-site cations within this framework, we synthesized a series of PNN–PMeN–PT (Me = Sc, In, Lu) ceramics. When Sc³⁺, In³⁺, and Lu³⁺ were introduced in equimolar proportions, the piezoelectric coefficient (d₃₃) increased from 938 pC/N to 1012 pC/N, aligning with high-entropy predictions. However, the maximum d₃₃ value of 1046 pC/N was achieved by deviating from this ratio, specifically with a higher fraction of smaller Sc³⁺ and a lower fraction of larger Lu³⁺. Analyses based on both Landau theory and fluctuating local polarization theory reveal that this asymmetric ionic ratio further enhances the distortion of piezoelectric functional cells, leading to the optimal performance. Electrical characterization and piezoresponse force microscopy confirm that the outstanding properties originate from a synergistic design: a globally disordered matrix established via multi-cation doping, augmented by local structural heterogeneity tuned through the Sc³⁺/Lu³⁺ ratio. Our findings highlight that advancing ultrahigh piezoelectricity systems requires deliberate engineering of the local piezoelectric functional cells.
