Such effects are commonly associated with non-paraxial focusing or light-matter interfaces. Here, we demonstrate that higher-order Poincaré modes carrying a tunable Pancharatnam topological charge ℓp enable deterministic control of SOI entirely in free space and within the paraxial regime. We show that modulation of ℓp drives a measurable radial separation of circular polarization components - a free-space optical Hall effect arising from propagation-induced mechanisms alone. The effect originates from differential Gouy-phase evolution and radial divergence between the two circular components of an initially spin-balanced vector beam. This identifies ℓp as a single, tunable parameter linking Pancharatnam topology to paraxial spin-orbit coupling, establishing a simple and material-independent route to generate and control optical chirality and SAM. This approach provides new opportunities for tunable optical manipulation, chiral sensing, and high-dimensional photonic information processing.\u0000\u0000The alternative text for this image may have been generated using AI.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Emerging thermally evaporated perovskites involving precise control impose even stricter requirements on the purity of the vapor atmosphere. Compared to the purified solvent for the reaction atmosphere in the solution-based method, efficient and effective vapor purification remains unexplored. Here, we report one-step vapor purification for a pure atmosphere with less than one percent detrimental impurity. The in-situ residual gas analysis was employed to emphasize the complexity of the gas-phase composition and reveal the impurity reaction competition during the purification. The pre-control of the vapor atmosphere enabled a record external quantum efficiency over 20% for a thermally-evaporated perovskite light-emitting diode (PeLED) based on defect-suppressed FAxCs1-xPbBr3 films. Moreover, the PeLED display panels exhibit over 5-fold and 2-fold magnification in operational and storage stability. The stability extension in OLEDs by this strategy demonstrates its universal effectiveness and commercialization potential for other types of thermally evaporated optoelectronic devices.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"207 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147726121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the inefficient harnessing of photoinduced hot electrons in conventional developed strategies greatly impede their therapeutic application in bone tissues. To overcome these challenges, we herein engineered a near-infrared II (NIR-II)-triggered plasmonic catalysis, which was fabricated through the integration of gold nanobipyramids (Au NBPs) with tip-deposited platinum nanoparticles (Pt NPs), for effective elimination of hypoxic bacterial biofilms on bone implants. The strategic deposition of Pt NPs at the tip of Au NBPs (ePt-Au NBPs) not only brought the redshift of the NIR absorption peak, but also accelerated charge separation and electromagnetic field localization, which endowed the ePt-Au NBPs plasmonic heterostructures with enhanced catalytic activity. Under NIR-II laser irradiation, the plasmonic catalysis with tip-localized enhancement enabled robust generation of hydroxyl radicals (•OH), thereby facilitating the cleavage of extracellular DNA (eDNA) within biofilms, disrupting biofilm integrity, and ultimately sensitizing bacteria to thermal ablation. These attributes collectively contribute to the effective elimination of hypoxic bacterial biofilms. Furthermore, surface functionalization with RGDC peptides conferred the implant with superior biocompatibility and osteogenic integration capabilities. This rationally designed plasmonic catalysis, combining the NIR-II-triggered simultaneous production of enhanced catalytic activity and localized hyperthermia, demonstrates significant potential for translational applications in light-responsive therapeutic strategies for implant-associated infections.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147702278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike conventional binary LC diffractive elements, our devices exhibit a smooth, continuous three-dimensional phase profile. Two devices were demonstrated with wrapped phase profiles of 2π and 4π radians, respectively. Polarized optical microscopy and digital holographic microscopy confirm that the polymerized regions follow the intended spatially varying phase distribution. Far field measurements show that the 2π rad FZP generates a strong focal spot at 0 Vpp and switches off at higher voltages. In contrast, the 4π rad FZP exhibits varifocal behavior, switching between two focal lengths: 24 mm at 0 Vpp and 48 mm at an intermediate voltage of 2.1 Vpp. At higher voltages, the focus disappears entirely. Compared to a binary FZP of equal size and focal length, the continuous phase design nearly doubles the focusing efficiency and enables switchable, compact, vari-focal, and energy-efficient optical components. This approach offers new opportunities for advanced applications such as augmented and virtual reality, adaptive optics, and other next-generation photonic systems.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147695034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, a novel achromatic imaging method was first proposed, utilizing the unique wideband consistency of diffracted Bessel spots combined with non-blind image restoration techniques. To address the off-axis aberration issue, off-axis achromatic meta-axicons with eccentric conical phases were further designed to convert oblique plane waves into wideband uniform off-axis Bessel beams. Ultimately, a single metasurface integrating 9 meta-axicons with different design field angles was developed, and a meta-camera was constructed accordingly. After image restoration, the meta-camera achieves achromatic imaging within a 10° stitched field of view (FOV), and an angular resolution close to that of near-diffraction-limit lens with the same aperture throughout the entire FOV. The core idea of achieving achromatic imaging based on natural dispersion laws in this study enables the wideband minimalist optical system based on metasurface to completely circumvent the aperture limitation, providing a highly valuable solution for large-aperture meta-camera design that can simultaneously accommodate wideband and off-axis FOV.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147695191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most high-performance ML systems rely on complex multicomponent compounds that often suffer from limited intensity, stability, and scalability, largely due to poorly understood mechanisms. Herein, we report a simple Al2O3:Cr3+ oxide that exhibits unprecedented ML intensity, enabled by a well-defined mechanical-to-optical energy conversion process. The self-recoverable ML arises from stress-induced ionization of electrons from luminescence centers, followed by their recapture upon stress release. By precisely tuning the doping levels, annealing conditions, and heterojunction interfaces, Al2O3:Cr3+ phosphors achieved intense, reproducible, and thermally stable near-infrared emission. Notably, high-temperature annealing dramatically enhanced the ML intensity, with thermodynamic and kinetic analyses revealing increases in the carrier and defect concentrations by several orders of magnitude, accounting for the exceptional brightness. By leveraging the chemical robustness, abundance, and low cost of alumina, we demonstrated the flexible ML paper for stress visualization and multi-level anti-counterfeiting, as well as in-situ grown Al2O3:Cr3+ luminescent layers on Cr-Al alloys for passive, real-time stress monitoring. This study establishes Al2O3 as a durable and scalable oxide platform for next-generation self-recoverable ML materials, bridging fundamental research and practical sensing technologies.","PeriodicalId":18069,"journal":{"name":"Light-Science & Applications","volume":"441 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147684981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
