Glasses are central to modern science and technology, yet conventional silicate, organic polymer, and metallic glasses share persistent limitations: energy-intensive processing and poor recyclability. To address these challenges, we report the large-scale synthesis of supramolecular glasses (SGs) from urea (UR) and ZnCl 2 via a facile grinding–heating–cooling process conducted within a deep eutectic solvent (DES) framework. During heating, the DES facilitates in situ UR polymerization, generating biuret (BU) and cyanuric acid (CA) intermediates that partially coordinate with Zn 2+ ions to yield entropy-stabilized amorphous glass networks. The resulting SGs exhibit excitation-wavelength-dependent ultralong phosphorescence with emission tunable across blue, green, and yellow. In addition to this photonic functionality, the SGs adhere strongly to diverse substrates (e.g., silicate glass, wood, and ceramics) and display exceptional flame retardancy. This combination of tunable luminescence, substrate adhesion, and flame retardancy positions the SGs as promising candidates for intelligent anti-counterfeiting labels, decorative coatings, and flame retardancy applications. This work thereby establishes a sustainable, scalable, and low-cost platform for producing multifunctional glass materials from commercially available precursors, with broad implications for photonics, smart materials, and surface protection.

A new mid-infrared fluoroaluminate-tellurite glass with low hydroxyl absorption coefficient and high visible-infrared transmittance was fabricated by the high temperature melt casting method. The melting equipment was innovatively designed by placing lift furnaces in the glove box filled with dry oxygen to assure waterless preparation. The glass prepared in the glove box had low hydroxyl absorption coefficients (0.09 cm −1 ), validating the effectiveness of the water removal equipment. The glass was obtained with excellent thermal stability (T g > 450 °C) and good resistance to crystallization based on thermodynamic analysis (ΔT > 100 °C). The transmittance of glass maintained 80–91.30 % from 371 to 5572 nm, achieving high transmittance in multi-waveband. The glass had excellent optical and composition homogeneity indicated by refractive index and EDAX. The results showed that this glass had high thermal stability, visible-infrared transmittance and optical homogeneity, making it a good candidate for multi-waveband optical window materials.

When employing the conventional melt quenching technique for the preparation of Mn 2+ -doped glasses, it is observed that Mn 2+ readily undergoes oxidation to Mn 3+ during high-temperature melting. Typically, researchers incorporate reducing agents into the synthesized raw materials or utilize a reducing atmosphere when preparing samples to mitigate this phenomenon. In this study, a novel approach was proposed to suppress Mn 2+ oxidation and enhance its luminescent properties. The zinc phosphoborate glasses based on 28.1P 2 O 5 –10.9B 2 O 3 –28.1ZnO (P–B–Zn) were prepared using the traditional melt quenching method. The effect of Cd 2+ on the red emission of Mn 2+ was studied by doping 2.9 mol% Mn 2+ and changing the concentration of Cd 2+ in the glasses. The analysis of photoluminescence emission (PL) spectroscopy and photoluminescence excitation (PLE) spectroscopy revealed a significant enhancement in the red emission resulting from the 4 T 1 (G) → 6 A 1 (S) transition of Mn 2+ under 409 nm excitation after doping with Cd 2+ ions. When the doping content of Cd 2+ is 19 mol%, the luminescence intensity of Mn 2+ reaches its maximum value, which is 4.24 times higher than that of undoped Cd 2+ . The results of the absorption and transmission spectra indicate a weakening of the 5 E g → 5 T 2g transition of Mn 3+ and an increase in the transparency of the glasses. The significant reduction in the absorption peak of Mn 3+ suggests that doping Cd 2+ can effectively inhibit the oxidation of Mn 2+ to Mn 3+ , as further confirmed by X-ray photoelectron spectroscopy (XPS) analysis.

Compounds with crystallization and vitrification capabilities can achieve more uniform grains with higher crystalline density after glass crystallization, improving the fluorescence properties of glass ceramics (GCs). In this work, a series of Tb 3+ -doped SrLa 2 Ga 4 Si 2 O 14 glasses and glass ceramics were prepared through traditional melt quenching and thermal treatment. The glass exhibits good transmittance and a sharp exothermic peak at 961 ºC. The photoluminescence and radioluminescence properties were studied in detail, and the Tb 3+ aggregation in glass and GC was discussed. Compared with the glasses, the opaque GCs show inferior fluorescence properties but better X-ray irradiated fluorescence, about 10% of the integrated emission intensity of the commercial BGO scintillation crystal. More precise processing in glass–ceramics towards homogeneous crystallization and good transmittance need to be addressed, and a promising scintillator with improved scintillating performance can be expected.

Electrochemical nitrate reduction to ammonia (NRA) is a promising approach for alleviating energy crisis and water pollution. Current NRA catalysts are challenged to simultaneously improve the rate of the adsorption and desorption processes to further increase the total activity due to the Brønsted−Evans−Polanyi (BEP) relationships. Herein, a two-step Joule heating method is utilized for the preparation of Ni 0.25 Cu 0.5 Sn 0.25 nanometallic glass containing synergistic catalytic sites to simultaneously enhance the adsorption and desorption processes. Kelvin probe force microscopy reveals a pronounced oscillatory behavior in the surface potential of Ni 0.25 Cu 0.5 Sn 0.25 nanometallic glass, which is an important feature of the synergistic catalytic site, and an empirical formula is proposed to quantitatively characterize its oscillatory characteristic. In situ electrochemical Raman spectroscopy indicates the promotion of nickel and tin atoms for nitrate adsorption and ammonia desorption processes, respectively. DFT calculations demonstrated that Ni 0.25 Cu 0.5 Sn 0.25 presents a wide range of adsorption energy distributions to favor the multisite synergistic catalysis. The present work provides new ideas for the design and understanding of highly active NRA catalysts.

Co-doping of Yb 3+ with Mn 2+ is a promising way to realize broadband up-conversion (UC) luminescence. The tunable broadband emission has been widely demonstrated in crystal materials, but the research on Yb 3+ /Mn 2+ co-doped transparent optical glass has been scare, especially in fluoride-based transparent glass ceramics (GC) that can realize the uniform ions incorporation and efficient UC emission. Herein, a series of Yb 3+ /Mn 2+ activated transparent fluorosilicate GCs containing perovskite KMgF 3 nanocrystals were successfully prepared, and the effect of heat-treatment process and/or Mn 2+ ion content on the UC luminescence modulation has been investigated. Our results show that the spontaneous crystallized precursor sample exhibits only a green emission at ~538 nm, while additional orange-emitting band centered at ~613 nm is noticeable in the GCs with the gradual precipitation of KMgF 3 nanocrystals after heat-treatment. The controllable luminescence can be assigned to the formation of Yb 3+ -Mn 2+ dimers that are located in multiple coordination environments provided by the glass matrix and crystalized nanocrystals. In addition, the prepared GC samples exhibit excellent reversible emission characteristics during heating and cooling cycles. This research not only provides a new option to design desirable coordination environment for Yb 3+ -Mn 2+ dimers, also helps to recognize the UC process in the transparent matrix in detail.

In this work, we firstly introduce a facile method to synthesize bulk silica glass contained indium tin oxide nanoparticles (ITO NPs). Water solution with InCl 3 and SnCl 4 was mixed and dipped into the mesoporous silica glass (MSG) followed by an in-situ growth of ITO NPs under 1000 °C heat treatment. X-ray diffraction (XRD) and transmission electron microscopy (TEM) show that the ITO NPs are highly monodisperse and crystalline in the silica glass with size around 20–30 nm. The size and distribution of ITO NPs can be regulated by the mesopores of mesoporous silica glass (MSG) effectively. The absorption and photoluminescence (PL) spectra exhibit an optical band gap and a PL emission of the ITO NPs doped silica glass at 3.12 eV and 560 nm, respectively. Results indicate that this kind of composite material has potential applications for optical nonlinearity, plasmonic formation, and sensing in the future.

A series of colorless and transparent (28- x )La 2 O 3 -72Al 2 O 3 : x Tm 3+ ( x = 0, 1, 1.5, 2, 3) luminescent glasses were successfully prepared by the containerless method. The effects of Tm 3+ substitution on the physical, thermal, optical and photoluminescence properties of La 2 O 3 -Al 2 O 3 glasses were investigated. X-ray diffraction confirmed the amorphous natures of the as-prepared glasses. Excitated at 354 nm, La 2 O 3 -Al 2 O 3 :Tm 3+ glasses emitted blue luminescence at 457 nm, corresponding to the 1 D 2 → 3 F 4 transition of Tm 3+ . These glasses showed high Vicker's hardnesses (7.2–8.8 GPa), and excellent thermal stabilities ( T g : 840–851 °C), which were both augmented with increasing content of Tm 3+ . They also exhibited high transmittances in a wide window ranging from 220 nm to 8.9 μm. In conclusion, the substitution of Tm 2 O 3 for La 2 O 3 increased the Vicker's hardness, thermal stability and transmittance window of La 2 O 3 -Al 2 O 3 glasses, allowing potential applications to optical devices in the visible to infrared region.

Aluminoborosilicate glasses doped with different types and amounts of rare earth oxides (Dy 2 O 3 , Eu 2 O 3 , and La 2 O 3 ) were synthesized via the sol-gel method. The impacts of doping these rare earth oxides on the glass structure, thermal, and dielectric properties were discussed. IR analyses showed that glasses doped with 2 wt.% La 2 O 3 contained more [BO 4 ] and [AlO 4 ], which optimized the polymerization degree of the glass network, and strengthened the structure. This glass had a lower dielectric constant (ε r = 2.27) and dielectric loss (tanδ = 0.0019) at 13 GHz. Additionally, the glass transition temperature (T g ), initial crystallization temperature (T c ), and thermal stability (△T) all increased with higher rare earth ionic radius (Dy 3+ , Eu 3+ , La 3+ ), due to decreased non-bridging oxygen levels (NBO) of [SiO 4 ] and increased [BO 4 ] and [AlO 4 ] in the glass grid. However, co-doped rare earth oxide glasses inhibited conversion from [BO 3 ] to [BO 4 ] when equal amounts of La 2 O 3 and Dy 2 O 3 or Eu 2 O 3 were added, which resulted in a looser glass network and a higher dielectric constant. As La 2 O 3 gradually replaced Dy 2 O 3 or Eu 2 O 3 , the dielectric constant initially increased and then decreased, ascribed to the shift polarization of RE 3+ in the glass structure.

For the treatment of tumor-related bone defects resulting from surgical resection, simultaneous eradication of residual tumor cells and repair of bone defects represent a challenge. To date, photothermal therapy based on photothermal materials is used to remove residual tumor cells under near infrared light. However, most of photothermal materials have no function for bone repair, and even if combined with bioactive materials to enhance osteogenesis, they still cause potential harm to the body due to inability to degrade or poor degradability. Herein, multifunctional bioactive glasses (PGFe5-1100, PGCu5-1100) based on phosphate glass doped with transition metal elements were prepared for photothermal ablation, bone regeneration, and controllable degradation. The glasses exhibited excellent photothermal effect, which was derived from the electron in-band transition after light absorption due to energy level splitting of doped transition metal element and the subsequent electron nonradiative relaxation. The photothermal performance can be controlled by laser power density, element doping content and glass melting temperature. Moreover, the hyperthermia induced by the glasses can effectively kill tumor cells in vitro. In addition, the glasses degraded over time, and the released P, Ca, Na, Fe could promote bone cell proliferation and osteogenic differentiation. Therefore, these results successfully demonstrated that transition metal element-doped phosphate glasses have multifunctional abilities of tumor elimination, bone regeneration, and spontaneous degradation simultaneously with better biosecurity and bioactivity, which is believed to pave the way for the design of novel biomaterials for osteosarcoma treatment.

In this work, a series of perovskite nanocrystals glasses with different concentrations of Tb 3+ doped CsPbI 3 , which have excellent characteristics in terms of water resistance and cyclic thermal stability, were prepared by melt quenching and in situ crystallization methods. With the introduction of Tb 3+ , the photoluminescence quantum yield of CsPbI 3 was greatly improved. Considering that the two fluorescence peaks of Tb 3+ and CsPbI 3 at different positions respond differently to temperature stimuli, we studied the potential application of those glasses as optical temperature detection tools in the temperature range of 80−480 K. More importantly, the results showed higher sensitivity than other tools, with the maximum absolute and relative temperature sensitivities reaching as high as 0.034 K −1 and 1.78 % K -1 , respectively. This work is expected to provide an effective method for the application of CsPbX 3 in high-performance optical temperature sensing materials.

The design of functional materials with tunable broadband luminescence performance is still of great interest in the fields of lighting, solar cells, tunable lasers, and optical amplifiers. Here, via a melt-quenching method, a series of bismuth (Bi)-doped germanium-borate glasses with composition of 40GeO 2 –25B 2 O 3 –25Gd 2 O 3 –10La 2 O 3 – x Bi 2 O 3 have been prepared, in which multiple Bi active centers can be stabilized simultaneously. Dual-modulating modes of visible (380-750 nm) and near-infrared (NIR) (1000-1600 nm) broadband photoemissions were effectively controlled under flexible excitation scheme. Photoluminescence (PL) spectra at low temperature 10-298 K were appropriately employed to interpret such an unusual wide visible emission band. To further illustrate the origin of NIR component, transmission electron microscopy (TEM) measurement was carried out. It is demonstrated experimentally that the visible emission mainly originates from the collective contribution of the 3 P 1 / 3 P 0 1 S 0 transitions of Bi 3+ , while the broadband NIR luminescence should be related to the formation of low valent Bi + and (or) Bi 0 centers. This work may help to enhance the knowledge of the complex luminescence mechanism for the Bi species and it also enables such transparent glass materials to be a promising candidate for the multifunctional tunable light source.
