Here, a low-temperature liquid metal-based synthesis method is used to fabricate β-(AlxGa1-x)2O3 nanosheets with tunable composition (x = 0–0.88). This approach enables selective aluminium enrichment in nanosheets while preserving the monoclinic crystal structure and adopting the (−201) orientation, similar to conventional β-Ga2O3 thin films. The synthesized nanosheets exhibit large lateral dimensions (>100 µm) and an average thickness of 3.2 ± 0.5 nm, making them suitable for nanoscale device applications. By varying the Al content from 0 to 10 at% in the liquid metal, the bandgap is tuned from 4.50 eV (pure β-Ga2O3) to 6.41 eV (β-(Al0.88Ga0.12)2O3). Molecular dynamics simulations provide insights into the Al enrichment mechanism at the liquid metal interface. The β-(AlxGa1-x)2O3 nanosheets retain key β-Ga2O3 characteristics, including self-trapped hole formation, ensuring structural and electronic integrity. The liquid metal synthesis method overcomes limitations of conventional deposition techniques, offering a scalable approach for tailoring 2D metal oxide properties and enabling bandgap-engineered optoelectronic applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 27","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501116","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A strategy to accomplish this has been to use surface plasmon polaritons (SPPs) in stacked doped/undoped semiconductor layers. Alternately, surface phonon polaritons (SPhPs) have emerged as a promising low-loss alternative. In this work, a phonon-driven type I HMM using ZnO/(Zn,Mg)O heterostructures is designed, demonstrating control over the hyperbolic behavior through the careful choice of Mg content and layer thicknesses. This study shows that increasing the Mg concentration in the ternary layers enhances type I behavior, while the optimal layer thickness varies depending on the Mg content. After analyzing the conditions for achieving type I hyperbolic dispersion, this concept is experimentally demonstrated with three samples. The structures are characterized by means of polarized reflectance spectroscopy and attenuated total reflectance spectroscopy is used to report the presence of a SPhP mode within the type I region. Employing the transfer matrix method, it is demonstrated that this mode exhibits negative frequency dispersion, a hallmark of type I hyperbolic modes, and isofrequency curve calculations further confirm this behavior. Controlling the design of a phononic type I HMM lays the groundwork for exploring low-loss, sub-diffraction-limited optical modes using SPhP excitations.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 26","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501095","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145038415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, micron-sized particulate Cs3Cu2I5 and Sb-Cs3Cu2I5 are synthesized using the anti-solvent method. For the first time, the broadband nonlinear optical properties of these materials in the near-infrared region are systematically investigated. Compared to pristine Cs3Cu2I5, Sb-Cs3Cu2I5 exhibited superior nonlinear optical performance, demonstrating a modulation depth of 17.7% and a nonlinear absorption coefficient of −(4.28 ± 0.05) cm MW−1 at 1 µm, as well as a modulation depth of 13.5% and a nonlinear absorption coefficient of −(3.25 ± 0.06) cm MW−1 at 1.5 µm. Capitalizing on its exceptional nonlinear optical response, Sb-Cs3Cu2I5 is employed as a saturable absorber in both Yb-doped and Er-doped fiber lasers. In the Yb-doped fiber laser, noise-like pulse mode-locking is achieved with a central wavelength of 1038.4 nm and a pulse width of 721 fs, while in the Er-doped fiber laser, conventional soliton mode-locking is realized with a central wavelength of 1557.7 nm and a pulse width of 853 fs.

Owing to the formation of type-II p-n junction, the device achieves large rectification ratio of 103 and current on/off ratio of 105.

Combing light and gate voltage as inputs, the device realizes an optoelectronic logic gate “AND”, indicating its information processing ability. Furthermore, the device also exhibits superior nonvolatility and multi-bit optoelectronic programmable characteristics. As results, the device can stimulate the synaptic plasticity, including short-term/long-term plasticity and paired-pulse facilitation.

Bismuth-based MOFs (Bi-MOFs) are not heavily explored yet but are highly promising in this regard. A robust defect-engineered Bi-MOF (namely, Bi-TATAB) is prepared under acid-modulator-free solvothermal conditions. Next, a series of lanthanide (Ln)-doped Bi-MOFs is obtained by incorporating either one or two Ln3+ ions (Ln3+ = Eu3+, Tb3+, Eu3+/Tb3+, Dy3+, or Sm3+) using a facile one-pot method. The resulting doped analogues show high crystallinity and porosity, good thermal resistance, and highly tunable luminescent properties. The color of the emitted light can be tuned by varying the dopant ions and their ratios. Thus, three white-light-emitting materials, including Eu3+ or Eu3+/Tb3+, are developed. The new material (Eu0.025Tb0.05Bi0.925-TATAB) exhibits temperature sensing capability over a broad temperature range (10–360 K). Two ratiometric temperature sensors are constructed based on two thermometry modes proposed for this MOF: ITb/IEu and IBi-MOF/IEu under single-wavelength excitation. Intriguingly, the latter system is among the most sensitive cryogenic MOF-based thermometers reported to date, with a maximum relative sensitivity (Sr) value of 8.84% K−1 (at 60 K). This material is the first example of a Ln/Bi-MOF platform with cryogenic temperature sensing properties.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
