In response to the urgent demand for windows with multi-mode self-calibrated temperature feedback operating over a wide range in extreme environments, herein, Pr 3+ –Er 3+ co-doped Y 2 Zr 2 O 7 (YZO) transparent ceramics were developed. After annealing treatment to remove defects, these ceramics exhibit high transparency and temperature-dependent wide-range photoluminescence, in which the in-line transmittance is up to 77.8% at 760 nm (theoretical limit is 78%), and the luminescence band spans blue to red. Furthermore, based on the luminescence intensity ratio technology, a multi-mode temperature sensing window using highly transparent YZO:Pr/Er ceramics was designed. The developed photothermal window shows relatively high sensitivity, in which absolute sensitivity ( S a ) and relative sensitivity ( S r ) reached 0.0105 K −1 at 363 K and 1.295% K −1 at 301 K, respectively. The developed thermometer could provide a reference for self-calibrated thermometer window, and its wide spectral operating range ensures the reliability of temperature measurement, which has the potential to be used in some extreme conditions.

Attaining effective warm white light emitting in functionally advantageous transparent polycrystalline ceramics is vitally important to guarantee the development of both human and botanical systems. In response to this aim, a series of Dy 3+ -doped Y 2 Zr 2 O 7 (YZO) transparent ceramics were prepared via a solid-state reaction and vacuum sintering approach in this work. These fabricated ceramics show high transparency, where the in-line transmittance at 700 nm is about 76%, which is very close to the theoretical limit (78%). In addition, under the excitation of UV light sources (358 and 384 nm), strong warm white light emissions were observed in these YZO:Dy transparent ceramics. The corresponding photoluminescence characteristics and mechanisms of YZO:Dy ceramics are investigated carefully. The Dy-doped YZO ceramics integrate with high transparency and UV-excitable warm white light emission properties, making them promising light-emitting converter materials for light-emitting source applications.

In this study, we synthesized Y2Zr2O7 (YZO): Bi3+/Eu3+ microcrystals through high-temperature solid-phase method. When the microcrystals were excited upon 263 nm and 329 nm, a tunable emission color variation from red to white is observed. The Correlated Color Temperature (CCT) of YZO: 6% mol Bi3+, 5% mol Eu3+ excited upon 329 nm is 4194 K, exhibited warm white light. Furthermore, the emission intensity of Eu3+ ion is remarkably improved by the incorporation of Bi3+ ion, due to the energy transfer from Bi3+ ion to Eu3+ ion. Their efficiency (ηT) in YZO: 6% mol Bi3+, 5% mol Eu3+ reaches 49.17%. The corresponding absolute quantum efficiency (λex = 329 nm) of YZO: 6% mol Bi3+, 5% mol Eu3+ is 56.21%. These results indicate that YZO: Bi3+/Eu3+ microcrystals are highly potential to enhance the industrial growth of photonics field, particularly the application of anti-counterfeiting and white light-emitting diodes.

At high temperatures, lightweight ceramic and aerogel materials have serious problems such as volume shrinkage, increased density, loss of flexibility, and decreased thermal insulation performances. The research on high-performance, lightweight, and flexible materials, which can meet the requirements of high-temperature applications, is a challenging topic in the industry. In this work, we developed a defective fluorite phase Y 2 Zr 2 O 7 flexible fibrous membrane (YZFM) material which has excellent thermal stability, no phase change until 1200 °C, and excellent flexibility until 1200 °C. The dense single fiber structure results in the tensile strength of the YZFM as high as 8.27 MPa. The low density (44 mg/cm 3 ), high porosity (99.2%), and excellent heat radiation reflectivity (750–2500 nm: Avg. 96.34%) endow the YZFM with outstanding thermal insulation performance (the thermal conductivity: 38 mW m −1 K −1 ). The 30 mm thick YZFM can reduce the high temperature of 1260 °C to 185 °C. The anisotropic layered structure makes YZFM have better acoustic absorption performance than commercial materials. These robust performances make our YZFM suitable for fields with strict requirements on material usage conditions, such as aerospace and cutting-edge industries.

Addressing the issue of carbon contamination during the smelting of specialty metals or alloys, utilizing graphite crucibles, has attracted considerable research attention, prompting the exploration of novel ceramic crucible materials. AlN ceramic, renowned for their exceptional high-temperature stability and resistance to corrosion, have emerged as promising candidates to mitigate this concern. Nonetheless, the limited mechanical properties and thermal shock resistance of AlN curtail its widespread application. In this study, Y 2 Zr 2 O 7 was introduced as an additive to enhance AlN's properties, and AlN-based composite ceramics were fabricated by employing pressureless sintering. The effects of Y 2 Zr 2 O 7 addition (3–10 wt%) on the mechanical properties and thermal shock resistance of the resulting composites were examined. The findings revealed that the incorporation of 5 wt% Y 2 Zr 2 O 7 (AlN-5YZO) led to the highest relative density and a refined grain structure , resulting in superior mechanical properties. Notably, the flexural strength , fracture toughness, and Vickers hardness of AlN-5YZO reached 322 MPa, 3.70 MPa m 1/2 , and 13.34 GPa, respectively. Furthermore, the presence of crack branching and crack deflection within the composite ceramics impeded crack propagation , effectively augmenting their thermal shock resistance. AlN-5YZO samples exhibited residual strength retention rates of 91.0 %, 84.2 %, and 76.7 % after 10, 20, and 50 thermal shocks between 1000 and 1600 °C, surpassing those of pure AlN. The findings of this study present promising avenues for advancing crucible materials tailored for high-temperature applications.

White LEDs are environmentally friendly light sources that have received extensive attention. The combination of an ultraviolet chip and three-color phosphors is the main method used to obtain white LED devices. The primary issues include the decrease in luminescent intensity and lifetime, the reduction in output power of the LED device, and the color shift of the phosphor in high-temperature environments caused by high operating currents and prolonged working times. In this work, bright single-phase full-spectrum white Tm3+ and Dy3+ Y2Zr2O7 (YZO) nanotubes with high thermal stability and ultralow color drift were prepared by electrospinning technique at 1300 °C. The color coordinates (0.3308, 0.332) of YZO: 2%Tm3+/2%Dy3+ nanotubes are very close to standard white light (0.33, 0.33). The luminescent properties of YZO:Tm3+/Dy3+ nanotubes were investigated and compared with those of YZO:Tm3+/Dy3+ powders prepared via a solid-state reaction at 1300 °C. At high temperatures, YZO:Tm3+/Dy3+ nanotubes exhibit better thermal quenching resistance than YZO:Tm3+/Dy3+ powders do because of their unique tubular structure. YZO:2%Tm/1%Dy nanotubes maintain 91.23% of their initial emission intensity at 453 K compared to 303 K, whereas the emission intensity of YZO:2%Tm/1%Dy powders remains at 90.42% at 453 K compared to that at room temperature. YZO: 2%Tm/1%Dy nanotubes have an ultralow color drift of 0.16% at 453 K, whereas that of YZO: 2%Tm/1%Dy powders reaches 0.9% at the same temperature.

In the most promising new window materials, the light-blocking property of the state-of-the-art transparent polycrystalline ceramics is still located in the UV range, which undoubtedly limits their applications. Herein, a transparent Y2Zr2O7:Tb (YZO:Tb) ceramic for light-shielding windows was prepared by a solid-state reaction and vacuum sintering method. Two simple and efficient routes, with doping concentrations varying and air-annealing temperatures regulating, were developed for the first time to control the content of defect clusters [TbY4+–O2––TbY4+] and [TbY4+–e•], enabling the optical cutoff waveband of these ceramics spanning from UV and BV to green light. These defect clusters generated from an air-annealing process were proposed for the relevant reaction mechanisms concerning light erasure behavior. The controllably tailoring of optical cutoff wavelength from Tb single-doped YZO ceramics, adjusted by defect clusters, may open a novel door to develop lanthanide-doped transparent ceramics for wide-range tunable light-shielding windows.

Obtaining detailed transmission and transition parameters of transparent materials is of vital importance for photonic engineering applications. In this work, we prepare a series of lanthanide active ions (Ln, Ln = Nd, Sm, Dy, Ho, Er, Tm) doped Y 2 Zr 2 O 7 (YZO) transparent ceramics through solid-state reaction method without any sintering aids, and its transmittance is very close to the theoretical limit. The Ln activator doping dependent refractive index , Abbe number, and theoretical transmission are investigated detailedly. Besides, the J-O intensity parameters Ωi (i = 2, 4, 6) of the prepared transparent YZO:Ln ceramics are obtained using J-O theory, and we elaborate on how the corresponding factors determine the variation of these parameters. Furthermore, combining theoretical calculations and spectroscopy characterization, this work provides a valuable reference of spectroscopic properties, such as spontaneous transition probabilities, radiation lifetime, and fluorescence branch ratio, in transparent lanthanide zirconate ceramics.

This study addresses the large-scale material requirements for plasma-facing components in fusion reactors. A scalable process was developed to produce W-Y 2 Zr 2 O 7 composite powders with a Y-to-Zr atomic ratio of 1:1, enabling batch production at the 20 kg scale. Bulk W-Y 2 Zr 2 O 7 composites were fabricated using SPS. The sintered composites exhibited tungsten grain sizes of approximately 3 μm, with second-phase particle sizes of about 200 nm within grains and approximately 500 nm along grain boundaries. The second-phase particles were identified as Y 2 Zr 2 O 7 . Tensile tests conducted at temperatures ranging from RT to 773 K revealed a DBTT between 573 K and 673 K, with the highest elongation after fracture (11.7 %) observed at 773 K. Compressive tests over the same temperature range showed a decreasing trend in yield strength with increasing temperature. Tensile simulations suggest that intragranular Y 2 Zr 2 O 7 nanoparticles can modify deformation pathways by impeding dislocation motion at elevated temperatures, providing an atomistic rationale consistent with the experimentally observed particle dispersion and mechanical response. Compressive simulations likewise indicate that such nanoparticles can constrain dislocation activity and contribute to the temperature-dependent strengthening trends. These findings offer valuable insights into the development of plasma-facing tungsten materials for fusion reactors.

A series of molybdenum (Mo) and cerium (Ce) co-doped Y 2 Zr 2 O 7 inorganic cool pigments were synthesized via a high-temperature solid-state reaction method. Substitution of Zr by Mo introduces interstitial oxygen into the lattice, leading to lattice expansion while enhancing the near-infrared reflectance of the pigments. Mo coexists in the form of Mo 6+ and Mo 5+ ions, with the yellow coloration primarily originating from Mo 5+ . The lattice expansion induced by the incorporation of larger Ce ions suppresses the formation of interstitial oxygen, thereby promoting an increase in Mo 5+ content, which results in a higher b* value while maintaining high near-infrared reflectance. The optimized composition (Y 1.55 Ce 0.45 Zr 1 Ce 0.65 Mo 0.35 O 7 ) exhibits the following chromatic parameters: L* = 88.26, a* = -3.19, b* = 55.15, and R NIR =93.68%. Furthermore, the simulation experiment revealed that the surface temperature of the coating based on the as-prepared pigment is 16.3 °C lower than that of the cement coating and 11.4 °C lower than that of the commercial iron yellow coating, demonstrating excellent solar reflective performance.

One-dimensional (1D) Y 2 Zr 2 O 7 :Er/Yb tube-in-tube nanostructures were prepared via a simple electrospinning technique with a single nozzle. The diameter of the outer tube of the Y 2 Zr 2 O 7 :Er/Yb tube-in-tube nanostructures is 190–170 nm, the thickness of the outer wall is 22–20 nm, the diameter of the inner tube is 120–100 nm, and the wall thickness of the inner tube is 17–14 nm. The optical properties of the Y 2 Zr 2 O 7 :Er/Yb tube-in-tube nanostructures, including the up-conversion and downshifting luminescence spectra, temperature sensitivity, and thermochromic properties, were studied in detail. Under 980 nm excitation, two weak green emissions at 528 nm and 550 nm, as well as a strong red emission at 650 nm of Er ions, are presented. When excited at 378 nm, the Er ions exhibit strong green emission at 545 nm, two weak red emission peaks at 650 and 680 nm, and near-infrared emission peaks at 1400–1600 nm. With increasing environmental temperature, the luminescence color of the 1D Y 2 Zr 2 O 7 :Er/Yb tube-in-tube nanostructures exhibited a transition from “orange→yellow→ green” when excited at 980 nm. For the 1D Y 2 Zr 2 O 7 :xEr/yYb tube-in-tube nanostructures (x = 0.01, 0.02, 0.03; y = 0.05, 0.10, 0.15), the maximum values of S r are 2.3 % K −1 under 980 nm excitation and 2.1%K −1 under 378 nm excitation within the temperature range of 303–723 K. This work develops integrated multifunctional optical materials and provides an alternative approach for the fabrication of nanoscale smart platforms, advanced displays, and applications in information security.
