Carbon dots (CDs), as an emerging nano-luminescent material, are promising candidates for long-persistence RTP due to their superior optical properties, low cost, minimal toxicity, and high stability. In this study, full-color, long-persistence phosphorescent materials are developed via a simple one-step hydrothermal method using p-hydroxybenzoic acid (p-HBA) as a precursor, by reacting with aromatic amines with different degrees of conjugation (o-phenylenediamine, 9,10-diaminophenanthrene, 1,8-diaminonaphthalene, and 1-aminopyrene). This approach achieves phosphorescence spanning a wavelength range from 432 to 601 nm, in which the longest RTP lifetime is 2.8 s and up to 23 s in the naked eye, without the need for organic materials using fluorescence resonance energy transfer. This is accomplished by modulating the graphite-N content and degree of conjugation of the CDs, as well as leveraging the dual-confinement of the B2O3 matrix. These materials exhibit robust long-persistence phosphorescence stability at room temperature in both organic solvents and cyclic excitation. Based on the excellent constant RTP performance and cyclic stability of the four composites, they can be widely used in advanced information encryption, anti-counterfeiting, and ASCII code information storage practical applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 20","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144606587","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}

This is essential for applications like LiDAR, beam-forming, and holographic displays, especially as devices reduce in form factor. Although a device with active beam-switching capability is a potential candidate for realizing those applications, there are only a few works to realize beam switching in reconfigurable metasurfaces with active tuning materials. In this paper, a multi-level beam-switching dielectric metasurface is theoretically presented with a graphene layer for active tuning, addressing challenges associated with achieving high directivity and diffraction efficiency, and doing so while using a single-gate setup. For two-level switching, the directivities reached above 95%, and the diffraction efficiencies are ≈50% at the operation wavelength λ0 = 8 µm. Through quasi-normal mode expansion, the physics of the beam-switching metasurface inverse-designed by the adjoint method is illustrated, highlighting the role of resonant modes and their response to charge carrier tuning. Under the same design scheme, characteristics of a three-level and four-level beam-switching device is designed and reported, suggesting a possibility of generalizing to multi-level beam switching.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 17","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202500236","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144299806","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, the present device structure-dependent photogenerated carrier transport and extraction still suffers from more serious challenges. Here, vertically oriented WS2 nanosheet arrays are prepared controllably via magnetron sputtering technique on an n-type silicon substrate, accompanied by a follow-up transversely distributed 2D MXene layer, to construct a dual orthogonal-stacked (DOS) heterostructure. This DOS strategy effectively utilizes the efficient charge transport channel properties inside a 2D-material plane to fundamentally suppress carrier recombination and promote efficient carrier transport and extraction. The photodetectors (PDs) demonstrate excellent broadband photoresponsefrom ultraviolet to short-wavelength infrared (254–1650 nm), achieving a photoresponsivity of 793 mA W−1, a high light-to-dark current ratio of over 103 at 500 nW cm−2, high response speeds (500 ns/31.1 µs) and a specific detectivity of 1.03 × 1014 Jones at zero bias. Additionally, the PDs maintain good long-term stability and repeatability under high pulsed light (500 kHz).

It significantly expands the design capabilities of 3D nanoprinting technologies based on 2PP-enabled direct laser writing (DLW). One key application is waveguide design, where the refractive index contrast between the core and the cladding materials determines light propagation properties. This study demonstrates the combination of 2PP and 1PP to fabricate photonic crystal fiber (PCF) segments, creating structures with a complex 3D refractive index distribution. Refractive index properties of commercially available IP-Dip and IP-S photoresins, commonly used in 2PP nanoprinting, are analyzed based on supplier data and previous research. Using these findings, PCF structures are designed to facilitate light propagation through either index-guiding (IG) or photonic bandgap (PBG) guiding mechanisms. The fabrication process is carried out using 2PP, exploiting the refractive index contrast between polymerized and unpolymerized resin regions. Subsequently, controlled UV exposure induces refractive index modifications in previously unpolymerized regions, enabling transitions between IG-to-PBG, PBG-to-IG, and IG-to-no guiding. This approach facilitates the fabrication of waveguides with tailored propagation properties, and by adjusting the PCF's transverse geometry and refractive index contrast, specific mode distributions can be achieved.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 19","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144551326","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}

Therefore, the development of optical components integrated into optical fibers is crucial. The ability to integrate metasurfaces into optical fibers has led to a greater number of degrees of freedom that might be used to realize all-in-fiber optical components. Here we explore the potential of plasmonic MSs based on a partial coverage of the phase range, introduced by Hail, but so far essentially unexplored. Exploiting this paradigm, we realize a beam splitter and a focusing lens at the tip of a single mode fiber operating in the near infrared. We show that partial-phase MSs, unlike their standard plasmonic counterparts, enable the generation of two beams, the ordinary and the anomalous one, that have the same polarization state and delivered power, allowing efficiencies of up to ∼30% to be achieved. Furthermore, we demonstrate that it is possible to focus light a few micrometers from the tip without the need of a beam expander. The realized meta-lens has a numerical aperture of 0.71 and a focusing efficiency of 20%, the highest efficiency achieved so far with a flat lens on a fiber tip.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 17","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202500263","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144299752","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}
