It was theoretically predicted that, for microspheres, electric and magnetic dipolar coefficients can simultaneously vanish by engineering the incident light, leading to the excitation of nonradiating hybrid optical anapoles. In this work, the experimental detection of hybrid optical anapoles in dielectric microspheres (TiO2) is reported using dual detection optical spectroscopy, developed to enable sequential measurement of forward and backward scattering under tightly-focused Gaussian beam (TFGB) illumination. The results show that the excitation of TiO2 microspheres (diameter, d ≈1 µm) under TFGB illumination leads to the appearance of scattering minima in both the forward and backward directions within specific wavelength ranges. These scattering minima are found to be due to vanishing electric and magnetic dipolar coefficients associated with hybrid optical anapoles. The ability to confine electromagnetic fields associated with hybrid optical anapoles can give rise to several novel optical phenomena and applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 27","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501315","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145110813","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}

The ability to nanopattern BP could enable new optoelectronic devices. However, existing nanopatterning techniques are either limited to thin flakes or produce BP with poor optical properties. Here, focused neon ion beam lithography is used to produce functional BP nanostructures. We demonstrate a “sketch and peel” method. The “sketch” step removes BP in a narrow line that outlines the desired structure. In the “peel” step, a hardened polymer droplet is used as a handle to pull off the surrounding flake. The “sketch and peel” method minimizes the damage to BP. We show that thermal treatment allows the small amount of damage that still occurs to be mitigated, as confirmed by Raman spectroscopy and mid-infrared photoluminescence. For the first time, this work demonstrates a method to nanopattern BP with very high resolution and to repair damage by producing high quality BP nanostructures. It thus could be an important enabling technology for future BP nanophotonic devices.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 27","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202500460","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145110828","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}

However, achieving a PGC thickness below 100 µm remains challenging due to its brittle nature. Herein, this work presents a novel strategy to fabricate an ultrathin cyan PGC for all-inorganic LEDs, based on our home-synthesized Ce-activated Ca2YAlGa2Si2O12 phosphor (CYAGS:Ce). The phosphor emits bright cyan light centered at λem 497 nm with a FWHM of 93 nm and an internal quantum yield (IQY) greater than 60%. The luminescence mechanism, including concentration and thermal quenching, is investigated in detail. Using tape-casting and low-temperature co-firing, an ultrathin PGC with a thickness of 98 µm is achieved. Structural and luminescence properties are compared to highlight the glass matrix's influence. Furthermore, based on as-prepared ultrathin PGCs, a compact LEDs with a low correlated color temperature (CCT, 3384 K) and high color-rendering index (CRI, Ra = 85.7) is obtained by integrating both red and cyan PGCs with a commercial 420 nm blue chip. This work advances the understanding of CYAGS:Ce cyan phosphor and provides a versatile strategy for fabricating ultrathin PGCs, highlighting their potential applications in all-inorganic LED lighting.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196558","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}

Properties that are not seen by the individual components, are investigated by an arsenal of steady-state and time-resolved techniques. These ranged from photoluminescence (PL) to ultrafast transient absorption spectroscopy (TAS) combined with global target analyses. Herein, charge separation from NCs to the electron-accepting PDIs upon photoexcitation of either the NC or PDI unities is evidenced. Remarkable is not only the lifetime of the charge carriers, which is on the time scale of microseconds, that is, 34 and 63 µs for NC@PDI-Ph and NC@PDI-PhPr, respectively, but also the control over their lifetimes through tuning phenyl- versus phenylpropyl-spacer length.

By optimizing crystal structures, particularly through the design of low-dimensional materials, the birefringence properties can be significantly enhanced. In this work, 1,10-phenanthroline is selected as the organic ligand, and d10 electronic configuration cation Zn2+ as the metal center, combined with Cl⁻ anions for structural regulation. Through this rational design, a novel 0D organic–inorganic hybrid metal halide (OIMH), (C₁₂H₈N₂)ZnCl₂, was successfully synthesized. (C12H8N2)ZnCl2 exhibits a large birefringence of 0.70@546 nm. First-principles calculations and structural analysis indicate that the anomalous birefringence originates predominantly from C−H···Cl hydrogen bonding between the [C12H8N2] and [ZnCl2], as well as their highly ordered spatial arrangement. Furthermore, (C₁₂H₈N₂)ZnCl₂ exhibits remarkable thermal stability (431 °C) and a short-wavelength UV cutoff edge (368 nm), achieving an optimal balance between birefringence and bandgap properties. This work provides fundamental insights into the rational design of high-performance birefringent crystals in low-dimensional OIMHs.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196613","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}

However, current millimeter-scale lateral dimensions of SC sheets (SC-sheets) fall short of practical requirements for large-area device integration, while their longitudinal mechanical flexibility remains un-quantified—a critical limitation that hinders flexible optoelectronic applications. This study demonstrates a breakthrough in on-chip fabrication of centimeter-scale Cs3Bi2I9 SC-sheets. By employing a self-developed organic polymer solution curing transfer technology, using poly(methyl methacrylate) (PMMA), centimeter-sized SC-sheets are successfully transferred intact onto flexible polyethylene terephthalate (PET) electrode substrate to construct a PMMA/Cs₃Bi₂I₉/Au/PET multilayered lateral PD. This architecture fully exploits the highly anisotropic electrical properties of Cs3Bi2I9 SC-sheets, achieving a device On-Off ratio of 3.3 × 10⁴ and specific detectivity of 2.55 × 10¹3 Jones under single-photon signals. Notably, experimental validation reveals that 1 µm-thick Cs3Bi2I9 SC-sheets exhibit a critical longitudinal bending radius of ≈2 mm. Even under super-threshold bending, fragmented crystal strips remain adhered to the electrode surface under PMMA/PET dual-layer confinement, sustaining PD functionality. Meanwhile, the confined encapsulation simultaneously confers 100% waterproofing.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 27","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145110814","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}
