As laser technology advances, the importance of laser protection puts an urgent demand for robust and high-efficient optical limiting materials. In this work, CsPbX 3 (X = Cl/Br, Br) NCs were synthesized by precisely controlling the ratio of Cl − to Br − and the heat treatment temperature, and the third-order nonlinear (TONL) optical properties of them were investigated systematically and deeply based on a nonlinear optical imaging technique with the phase-object (NIT-PO) at 532 nm for the first time. All of them demonstrate strong reverse saturation absorption (∼10 -12 –10 -11 m/W), and the sign of TONL refraction index (γ) relates to the component (CsPb(Cl/Br) 3 NCs glasses: ∼10 -20 m 2 /W, CsPbBr 3 NCs glasses: ∼−10 -20 to 10 -19 m 2 /W). In addition, they have excellent characteristics of thermal stability and water stability, as well as photostability under 455 nm laser irradiation, indicating that it is a promising optical limiting material.

Currently, the application of all-inorganic cesium lead halide perovskite (CsPbX 3 , X = Cl, Br, I) quantum dots (QDs) is limited due to toxicity of lead and poor ambient stability. In our work, a series of Ti-doped CsPbI 3 QDs were successfully prepared in borosilicate glass (SiO 2 -B 2 O 3 -ZnO) by the melt quenching and in situ crystallization technique. The samples showed excellent water/thermal stability, and the tunable emission (650–695 nm) was controlled by different Ti contents and heat treatment temperatures. In particular, the optical properties of CsPb 1− x Ti x I 3 QDs@glasses (x ≤ 0.5) are superior to those of pristine CsPbI 3 QDs@glass. As a result, the wLED was assembled using red-emitting CsPb 1− x Ti x I 3 QDs@glasses and yellow-emitting Ce 3+ :YAG phosphor under excitation of InGaN blue chip, which demonstrated an outstanding luminous efficiency of 102.44 lm/W, a high color rendering index of 80.6. Particularly, Ti-doped CsPbI 3 QDs@glasses with red and far-red light are combined with a blue-chip to assemble an LED device, which exactly satisfies the lighting conditions of plant growth.

Heavy metal pollution, particularly Pb 2+ , poses a severe threat to human survival and ecosystem health due to its detrimental effects on organisms. Therefore, evaluating the concentration of Pb 2+ in the environment can help mitigate these risks in advance. In this study, Cu nanoparticles (Cu NPs) modified 2D Cu-Metal-organic frameworks (Cu(NPs)/Cu-MOFs@ITO) are prepared and loaded onto indium tin oxide (ITO) glass by an electrophoretic method to produce an electrochemical sensor (ECS) for Pb 2+ . Cu(NPs)/Cu-MOF-B was synthesized by a simple solvothermal method and characterized by XRD, SEM, TEM , Raman, FT-IR and other methods to analyze the crystal structure, molecular structure and microstructure. The Cu NPs improve the electron transfer ability, and the abundant surface amino groups of Cu-MOF can be used to bind Pb 2+ characterized by CVs and EISs. The excellent energy positions of valence and conduction bands of Cu(NPs)/Cu-MOF facilitate the electron migration in oxidation and reduction of Pb 2+ analyzed by XPS, Mott-Schottky and UV–vis absorption curves. The limit of detection (LOD) reaches 0.065 μM and the sensitivity reaches 99.04 μA μM -1 cm -2 . The Cu(NPs)/Cu-MOFs@ITO ECS can be successfully applied to detect Pb 2+ in water environments with high sensitivity, selectivity and reproducibility, which provides a feasible method for detecting Pb 2+ .

Self-assembled monolayers (SAMs) technology is considered a potential surface modification technique for addressing challenges in micro/nanostructure fabrication. Bulk metallic glasses (BMGs) are ideal materials for micro/nanostructure moulds. In this study, the surface of Zr-based bulk metallic glasses (Zr-based BMGs) was modified using phosphonic acid SAMs. The findings indicate that phosphonic acid SAMs can effectively reduce the surface free energy of Zr-based BMGs, successfully converting its surface from hydrophilic to hydrophobic and significantly reducing its friction coefficient by up to 90.0 %. Moreover, compared to traditional crystalline Zr-3 alloy, SAMs technology provides significantly better modification effects on amorphous Zr-based BMG surfaces. Experimental results show that among the three different SAMs, the packing density is highest for the mixed hexylphosphonic acid–dodecylphosphonic acid (HPA–DDPA) SAMs, followed by pure dodecylphosphonic acid (DDPA) SAMs, with pure hexylphosphonic acid (HPA) SAMs showing the lowest packing density. The water contact angle for HPA–DDPA SAMs reaches 101.4°, representing a 68.7 % increase compared to the bare plate. Additionally, phosphonic acid SAMs can significantly reduce the friction coefficient of Zr-based BMG surfaces, effectively suppressing oxidative wear and abrasive wear , thereby improving surface wear resistance. The packing density of phosphonic acid SAMs is the primary factor influencing surface wettability and frictional performance, with both wettability and frictional performance increasing monotonically as packing density increases. This is attributed to shear forces and van der Waals forces at the interface. Under specific loads, HPA–DDPA SAMs exhibit excellent lubrication and wear resistance, attributed to the elastic response and compliance of the SAMs. In conclusion, this paper successfully prepares various phosphonic acid SAMs on Zr-based BMGs surfaces and provides a detailed elucidation of the enhancement mechanisms in hydrophobicity and wear resistance through the study of SAMs molecular packing density.

Glass matrices with high waste load capacity, stability, and economic viability holds significant technological implications for efficient and safe nuclear waste immobilization. Aluminosilicate glasses with various Si/Al molar ratios were successfully prepared by incorporating Al 2 O 3 into natural granite, effectively enabling precise regulation of the Si/Al ratios and overcoming the challenge of achieving complete vitrification. Here, we report a glass waste form with ultra-high CeO 2 loading (up to 20 wt .%) that exhibits excellent structural stability. At a Si/Al molar ratio of 3:1, cerium can incorporate into the glass network by forming Ce-O bonds through coordination with oxygen atoms in the [AlO 6 ] units. [AlO 6 ] is converted to more stable [AlO 4 ], thereby enhancing the stability of the glass. Up to 20 wt .% CeO 2 (9.62 mol%) can be fully incorporated into the glass system, where approximately 79.71 % of the bridging oxygen atoms form stable Si-O-Si and [AlO 4 ] units, contributing to a structurally robust glass network. The Ce-O bond length in the glass matrix is shorter (2.27 Å) than in CeO 2 , confirming enhanced coordination stability and aligning with superior chemical durability and mechanical properties. This work highlights the critical role of the Si/Al molar ratio and establishes low-cost granite could serve as a viable host material for nuclear waste immobilization.

The present work investigates the influence of borosilicate glass network polymerization on the structural, magnetic, and optical behavior of Ni 2+ ions. Borosilicate glasses containing a fixed concentration of NiO were synthesized using the melt-quenching technique with systematic substitution of B 2 O 3 by SiO 2 . XRD confirmed the amorphous nature of all samples, while FTIR spectroscopy revealed a progressive transformation from a borate-rich to a silicate-rich network, characterized by an increase in BO 4 units and a marked reduction in non-bridging oxygens (NBOs). Density and molar volume analyses supported the formation of a more compact and polymerized glass network with increasing SiO 2 content. EDX results verified the homogeneous incorporation of constituent elements within the glass matrix. Electron paramagnetic resonance (EPR) spectra exhibited broad and asymmetric signals characteristic of Ni 2+ ions in distorted octahedral coordination. A gradual decrease in EPR signal intensity and a slight narrowing of linewidth were observed with increasing SiO 2 concentration, attributed to reduced dipole–dipole interactions and enhanced spin–lattice relaxation in a more polymerized network. Optical absorption spectra showed characteristic spin-allowed transitions of Ni 2+ ions, accompanied by systematic redshifts of absorption bands with increasing SiO 2 content. Ligand field analysis revealed a decrease in the Racah parameter (B) and nephelauxetic ratio (β), indicating enhanced covalency of the Ni–O bonds due to increased glass network connectivity and reduced NBO concentration. The strong correlation between FTIR, EPR, and optical results demonstrates that the local electronic structure of Ni 2+ ions is governed by glass network polymerization, highlighting the tunability of borosilicate glasses for optical and photonic applications.

In this study, we successfully prepared quaternary germanate glasses (Ba x/3 Sr x/3 Ca x/3 )Ge (1-x) O 3 (x = 0.1–0.5) using a containerless solidification method. The structure of the germanate amorphous materials was characterized using techniques such as XRD, SEM, TEM and Raman. We evaluated the thermodynamic properties of the amorphous materials using differential scanning calorimetry and investigated their crystallization activation energies. In terms of application performance, we measured electrical conductivity and impedance spectra for the electrical properties, while the optical properties were assessed through the refractive index and transmittance. The results revealed that the (Ba 0.2/3 Sr 0.2/3 Ca 0.2/3 )Ge 0.8 O 3 system represented the germanium anomaly point. Due to the highest number of ternary rings and the most compact structure within this system, the values of density, glass transition temperature, refractive index, and bandgap all reached their maximum. As the content of alkaline earth oxides increased, the glass network structure gradually fractured, leading to an increase in non-bridging oxygens and corresponding changes in properties.

Tellurite glasses with the composition 67TeO 2 -3Al 2 O 3 -xZnO-(30-x)Na 2 O (x = 0–20 mol%) were synthesized via melt-quenching. Raman analysis revealed Al/Zn synergistically strengthened the network via Al-O-Te/Zn-O-Te bonds below 15 mol% ZnO, whereas excess ZnO triggered Zn 2+ /Al 3+ site competition, reducing crystallization resistance. The glass with 15 mol% ZnO (TANZ) shows optimal thermal stability ( T g = 311 °C, ΔT = 139 °C) and serves as the host for obtaining mid-infrared emission. The Ho 3+ /Yb 3+ co-doped TANZ glass shows high absorption and emission cross-sections of 7.36 × 10 –21 cm 2 and 5.86 × 10 –21 cm 2 , respectively, along with a long lifetime of 1.33 ms at 2 μm. These results highlight the potential of TANZ glasses as robust gain materials for mid-infrared fiber lasers.

Encapsulation of metal halide perovskite quantum dots (QDs) inside an inorganic glass matrix offers an effective route to address the stability issue, while the tuning of the luminescence performance across the full series of CsPbX 3 (X = Cl, Br, I) QD in a single glass system remains challenging. Here, by tuning the fraction of the two-dimensional (2D) network structure in a borosilicate glass system, we demonstrate the growth of CsPbX 3 (X = Cl, Cl/Br, Br, Br/I, I) QDs with controllable optical properties. Results indicate that as the halide ion radius increases, the optimal B 2 O 3 concentration corresponding to the maximum fluorescence intensity gradually increases, with the proportion of 2D network structures in the glass rising accordingly. Furthermore, CsPbX 3 QD glass fibers were further fabricated via high-temperature melt-drawing process. By optimizing the heat treatment parameters and fiber length, the optimal light transmission performance was determined. Finally, a self-calibrated temperature sensor based on the fluorescence intensity ratio (FIR) technique was successfully developed by incorporating Sm 3+ ions. The sensor delivers exceptional sensitivity and stability, with a maximum relative sensitivity of 0.030 K −1 at 370 K. This study not only confirms the critical role of the glass network in glass design but also provides a feasible technical pathway for developing a new generation of stable and efficient perovskite optoelectronic devices.

Silica glass exhibits significant application potential in advanced computing chip substrates, panel-level packaging (PLP), and three-dimensional heterogeneous integration owing to low dielectric constant and loss, superior mechanical properties, and exceptional thermal stability. However, the practical deployment of silica glass substrates is hindered by conventional melt-based processing, which is characterized by high complexity, excessive costs, and limited flexibility for rapid prototyping. In this work, an innovative strategy combining rapid shaping and low-temperature sintering is employed to fabricate a sintered silica glass with properties comparable to those of commercial fused silica, enabling rapid and customizable preparation of high-performance glass substrates for chip packaging process validation. The obtained photopolymerization–sintered silica glass exhibits low dielectric constant of ∼3.8 and loss on the order of 4 × 10 -4 in the microwave frequency band, together with high Young’s modulus of ∼73 GPa, good fracture toughness of ∼1.41 MPa·m 1 ᐟ 2 , and ultralow coefficient of thermal expansion on the order of 0.1 ppm·K -1 , which are superior to commercial TGV glasses such as SCHOTT AF32 and BF33. This approach is expected to provide a viable and flexible pathway for the development of next-generation advanced packaging technologies.

The consumption of Se-rich foods is a highly effective means of augmenting a person’s intake of Se, which plays a critical role in human health; however, excessive Se consumption can be toxic. The determination of Se levels is therefore of paramount importance to ensure the safety of both the production and consumption of selenium-rich foods. In this study, a rapid and user-friendly method is developed for the analysis of selenium-rich foods wherein the detection process is similar to watching three-dimensional movies in a theater. A portable 3D-printed colorimetric device called the Detection THEATER ( T ime-saving, H igh-sensitive, E asy, A ccurate, T elling, E conomical, and R apid) is first constructed for the rapid and visually accessible colorimetric analysis of samples in nonlaboratory settings. Subsequently, the Co-N-C nanozyme is doped with Pt to produce a Pt-Co-N-C nanozyme with superior peroxidase-like activity, which serves as the viewing glasses for signal amplification in the Detection THEATER. The Detection THEATER exhibits excellent sensitivity and accuracy, including a linear range of 0.5–1.2 μg/mL and a low detection limit of 0.026 μg/mL. The pretreatment of food samples is also optimized and simplified, thereby reducing processing times three-fold and enhancing accessibility and usability. The Pt-Co-N-C nanozyme-based Detection THEATER, demonstrated outstanding specificity and practicality, opening up a new avenue for the analysis of selenium-rich foods.

A family of highly thermal chromatic stable Dy 3+ -Eu 3+ doped B 2 O 3 -Bi 2 O 3 -ZnO-Li 2 O (BBZL) glass samples was synthesised using the high-temperature melt quenching technique. The optical and thermal stability properties of the samples were analysed using their fluorescence spectra at various temperatures, fluorescence lifetime decay times and colour coordinates. The Dy 3+ -doped BBZL (BBZL: Dy) glass samples generated cold white light when exposed to ultraviolet (UV) light, while the Dy 3+ -Eu 3+ -doped BBZL (BBZL: DyEu) glass samples emitted neutral and warm white light, which can be attributed to the introduction of Eu 3+ that substantially enhanced the colour rendering of samples. An overlap of the excitation-emission spectra of Eu 3+ and Dy 3+ indicated an energy transfer between Dy 3+ and Eu 3+ . Under a 350 nm excitation, the fluorescence lifetime of BBZL: DyEu decreased from 0.5348 to 0.3642 ms. Using the Dexter theory, the energy transfer between Dy 3+ and Eu 3+ was demonstrated to be an electric dipole-electric dipole leap. The chromaticity shifts of BBZL: DyEu were 8.60 × 10 −4 and 9.40 × 10 −4 at 448 and 498 K, respectively, reflecting the high thermal stability of the sample chromaticity. The study demonstrated that Dy 3+ -Eu 3+ doped borate glasses can be used as tunable luminescent materials in high-power white light-emitting diodes to mitigate the chromaticity shift in fluorescent materials at high temperatures.
