The key enabler of this work is ion beam processing at an angle sufficiently off-normal incidence, inducing self-assembly of a deposited metal layer into quasi-linear metallic features that can function as an etching mask. As a result, a fused silica metasurface, monolithic to the underlying substrate, is demonstrated at 375 nm wavelength to exhibit a phase delay angle of 30° between the principal axes. The capability of an angled etch mask replenishment process is also demonstrated for achieving deeper etch depth and for increasing the grating period, another first – to the best of the knowledge. This is the first display of a technology capable of fabricating glass-engraved near-linear grating structure with a feature-to-feature period as small as 118.6 nm. Furthermore, this technology has the potential to generate grating-like structures with periods as small as 12.4 nm, as demonstrated here with reactive ion beam processing assisted mask assembly. These structures are shown to have reflectivity < 0.4% across the wavelength band 350 nm – 1000 nm. Such a technology can enable laser-durable grating structures for the deep-UV and even down to soft X-ray wavelengths.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 12","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861563","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}

Their properties depend heavily on the choice of the inorganic lead halide framework and the surrounding organic layers. Recently, the introduction of chiral cations into 2D perovskites has attracted major interest to induce chirality and tune the chiro-optical response. Importantly, their optical properties are dominated by tightly bound excitons that also serve as primary carriers for energy transport. The mobility of photo-injected excitons is thus important from the perspectives of fundamental material properties and optoelectronic applications, yet remains an open question. Here, exciton propagation in 2D chiral perovskites is demonstrated using transient photoluminescence microscopy and density-dependent transport over more than 100 nanometers at room temperature is revealed with diffusion coefficients as high as 2 cm2 s−1. Two distinct regimes of initially rapid propagation and subsequent localization are observed. Moreover, perovskites with enantiomer pure cations exhibit faster exciton diffusion than the racemic mixture, correlated with the impact of the material composition on the disorder. Altogether, the observations of efficient exciton diffusion highlight the potential of 2D chiral perovskites to merge chiro-optical properties with strong light-matter interaction and energy transport.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 11","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202402606","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831381","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 traditional pulp is often considered low-value due to its limited potential for innovation. For instance, conventional pulp retains a brownish color from residual lignin, which restricts its effectiveness in applications that require cooling properties. While bleaching processes can produce white pulp with enhanced solar reflectance, it does not meet the growing demand for colored cellulose products. This study presents a scalable solution that leverages fluorescence to create colored cellulose pulp, enabling the preservation of vibrant colors while mitigating thermal stress. By harnessing photoluminescence with Stokes shift, this approach reduces solar heating effects, achieving cooling powers of 50–130 W m−2 and temperature drops of 7–11 °C under sunlight. Furthermore, as the fluorescence-treated process is fully compatible with large-scale manufacturing, this enhanced thermal management capability significantly expands the potential applications of cellulose-based materials across various industries.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 11","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202402827","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831384","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 structural water triggers the surface reduction of tungsten at a relatively low reduction potential, which governs the selective regulation of NIR light. The fast electrochemical kinetics and negligible structural destruction during the surface redox process enable fast and ultrastable NIR regulation. Increasing the reduction potentials, the Al3+ intercalates into the lattice, accompanied by injection of electrons, resulting in the formation of polaron absorbing visible light. The high charges and small radius of Al3+, and the enlarged ion diffusion channels by structural water synergistically facilitate the ion insertion/extraction, leading to enhanced EC performance in the visible light region. The tungsten oxide hydrate film is used as a working electrode to pair with an electrocatalytic counter electrode, with the presence of redox couples in Al3+ based electrolyte, to form a full EC device that exhibits NIR selectivity of 0.66, and cycling stability of 20 000 cycles in NIR region and 8000 cycles in visible region, which enables to design and fabricate large-size high-performance dual-band EC smart window for controllable management of solar heat and light.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 12","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861974","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, achieving stable, ultra-long afterglow emission remains a challenge, primarily because of the limitations of triplet exciton phosphorescence. This paper presents a novel Mn2+-doped NH4CdCl3 perovskite single crystal with ultra-long red afterglow emission. By introducing defect states through doping, afterglow emission is realized independently of triplet exciton phosphorescence. Under 254 nm excitation, the crystal exhibits a red afterglow lasting up to 2400 s, with controllable trap depth and concentration by adjusting the Mn2+ doping levels, thus tuning the afterglow duration. Additionally, the crystals demonstrate excellent photoluminescence (PL) under high-temperature and humid conditions. Information encryption patterns are also developed based on materials with varying doping concentrations, demonstrating their potential for anti-counterfeiting and encryption applications. This study provides a new strategy for achieving ultra-long afterglow in organic–inorganic hybrid perovskites.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 11","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831485","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}
