This study investigates the effect of SnO₂ addition on the structure and properties of the V₂O₅-TeO₂-CuO low-melting sealing glass. Six glasses (S1–S6) were prepared with nominal SnO₂ additions of 0, 5, 10, 15, 20, and 25 mol per 100 mol base glass. ICP-OES analysis revealed that the SnO₂ contents increased with nominal addition, while showing measurable differences from the nominal batch compositions. The structural evolution of these sealing glasses was investigated by Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy (Raman), and X-ray photoelectron spectroscopy (XPS) analyses. It was demonstrated that [VO₅] and [TeO₃] structural units were transformed into [VO₄] and [TeO₄] configurations with the progressive addition of SnO₂. The thermal expansion coefficient (CTE) of the sealing glasses was reduced from 105 × 10⁻⁷/°C to 86.4 × 10⁻⁷/°C, thereby improving the compatibility with the glass substrate (92 × 10⁻⁷/°C). Based on the flowability tests, S3 was identified as the optimal composition, with desirable fluidity achieved at 380°C.

In accordance with the electrical neutrality principle and defect recombination rules, intrinsic point defects and extrinsic impurity species inside KDP lattices tend to assemble into defect clusters. On this basis, taking the experimentally verified Fe-doped K-site substitutional defect associated with hydrogen vacancy complexes as a representative model, we systematically investigate the aggregation behavior of defect clusters in KDP crystals via first-principles calculations. Based on the calculation of defect formation energy (DFE), the -1 charged defect clusters are considered to exist stably. This conclusion is further verified by our investigations on lattice distortion and density of states (DOS). The calculated absorption peaks corresponding to the electron transitions from the -1 charged defect state to the conduction band minimum (CBM) and from the neutral defect state to the CBM are 230 nm and 271 nm, respectively, which are in good agreement with the experimental values (225 nm and 275 nm). In addition, analysis of the configuration coordinate diagrams reveals that electron transition from this defect state to the conduction band minimum (CBM) induces a relatively large lattice relaxation energy. Studies on cluster aggregation indicate that the DFE reaches its minimum value of 7.344 eV when the two clusters are in the next-nearest neighbor configuration with an intercluster distance of 6.39 Å. This result validates the rationality of the defect cluster aggregation model. Furthermore, analysis of lattice distortion and Bader charge distribution reveals that differences in the interaction strength between defect clusters and their surrounding lattice atoms constitute the dominant driving force underlying cluster aggregation. By calculating the binding energies corresponding to the aggregation of neutral and charged defect clusters, we confirm that charged defect clusters can readily aggregate and maintain thermodynamically stable configurations. Thus, a multiphoton transition and cluster aggregation model involving defect clusters V_H-Fe_K-V_H under laser irradiation is proposed.</p>\u0000 </div>","PeriodicalId":200,"journal":{"name":"Journal of the American Ceramic Society","volume":"109 7","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148386111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, erbium-doped indium-germanate oxyfluoride glasses exhibiting good glass-forming ability under conventional melt–quenching conditions were synthesized and converted into transparent glass-ceramics through controlled heat treatment near the glass transition temperature. All compositions exhibit weak hydroxyl absorption (&lt;0.3 cm⁻¹) and wide optical transparency from the ultraviolet to the mid-infrared. Ceramization selectively induces the precipitation of SrF₂ nanocrystals without significantly altering the glass transition temperature or refractive index. Structural analyses reveal uniformly distributed SrF₂ nanocrystals with characteristic sizes below ∼40 nm and suggest partial incorporation of Er³⁺ ions into fluorine-rich crystalline environments. Based on Vegard-law analysis of the X-ray diffraction lattice parameters using orthorhombic ErF₃ (Pnma) as reference, the erbium concentration within the SrF₂ nanocrystals is estimated to reach up to ∼8 at.%. The associated visible transmission losses are attributed to Rayleigh scattering from the nanocrystalline domains. Spectroscopic measurements show that nanocrystallization modifies the local environment of Er³⁺ ions, leading to reduced inhomogeneous broadening, resolved Stark splitting, and enhanced emission intensity and lifetimes at both 1.5 and 2.7 µm. In particular, part of the 2.7 µm emission exhibits lifetimes extending from a few hundred microseconds in the precursor glass up to 1.77 ms in the glass-ceramics. The luminescence enhancement is attributed to the presence of fluorine-rich low-phonon-energy environments associated with the SrF₂ nanocrystals, which reduce multiphonon relaxation rates. Time-resolved studies indicate the coexistence of two erbium environments in the glass-ceramics, corresponding to ions located in the oxide glass matrix and in fluorine-rich and/or crystalline surroundings. Despite crystalline fractions remaining below ∼6.2%, millisecond-scale lifetime components reaching 1.77 ms are observed at 2.7 µm, demonstrating that redistribution of only a small fraction of Er³⁺ ions toward fluorine-rich/crystalline environments is sufficient to induce pronounced changes in the luminescence response.
