The related materials built of uranyl cations, UO22+, remain unexplored, despite their tunable photoluminescence. While recently, bimetallic coordination and supramolecular systems built of cyanido metal complexes have proven a successful pathway toward stimuli-responsive materials, their combination with uranyl species is limited. Here, the construction of novel uranyl-based systems demonstrating a distinct sensitivity of emission to solvent vapors is reported, which is achieved by generating metal–organic, i.e, uranyl–2,4′-bipyridine-N,N’-dioxide, chains that are arranged into a porous supramolecular framework by metallophilic interactions between attached tetracyanidometallates(II), [MII(CN)4]2− (MII = Pd, 1; Pt, 2). Both resulting materials reveal reversible single-crystal-to-single-crystal transformation upon removal of crystallization solvent molecules, which is due to the flexibility of metallophilic interactions forming a porous metallophilic framework resembling MOF-74. The presence of infinite channels introduces sensing capabilities to water vapors while the emissive character leads to the humidity-variable emission characteristics, including the strong variation in emission intensity and lifetime. The obtained systems exhibit repeatable adsorption and emission characteristics, meeting the criteria for luminescent sensors.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 12","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861382","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}

The image formed in this manner can be viewed with the naked eye without the need for any wearable device. The volumetric display generates a 3D image that is real in size and appears to be a vivid object that can be viewed from any direction, allowing the viewer to interact with the image. A volumetric display technique based on light-emitting colloidal quantum dots (CQDs) is developed, thanks to their flexible assembly capability, low heat conductivity, and attainable high photoluminescence quantum yield (PLQY). This approach uses a single laser beam to create a 3D display with a micrometer resolution. The effect of CQD's heat capacity and heat conductivity on the microsphere's photophoretic force (PPF) is investigated, and the results suggest that only heat conductivity has a significant impact on the PPF. It is also discovered that the shape and size of the microsphere have a great impact on the PPF; microspheres with a diameter comparable to the size of the optical trap, or with a nonspherical shape, are more easily captured.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 8","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622601","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, the color saturation of these synthetic structures is often diminished by incoherent scattering caused by defects and irregularities. The inclusion of absorbing materials increases color saturation, but where this absorber is most efficiently incorporated within a photonic structure remains unknown. Here, this question is addressed using predictive design. A mathematical structure optimization algorithm is developed that iteratively places absorbing particles within a colloidal photonic crystal until an optimal distribution that produces maximum chroma values is identified. This rigorous optimization shows that placement of the absorbing material in the bottom layers of the photonic structure is most efficient in producing highly chromatic structural colors compared to other common absorber placements. Experiments based on a layer-by-layer assembly of polystyrene@polydopamine core–shell particles with controlled absorber distribution confirm these findings. These results demonstrate the ability of predictive design to guide the experimental realization of structurally-colored materials with optimal properties without the need for time- and resource-consuming experimental parameter studies.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 12","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202403279","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861498","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}

For light-emitting applications grain sizes in the sub-micrometer-range have previously shown enhanced brightness. It is therefore crucial to develop simple, yet reliable methods to produce such films. Here, a solution-based synthesis protocol for the on-substrate formation of MAPbBr3 (MA = methylammonium) nanostructures by adding the bifunctional rac-3-aminobutyric acid to the precursor solution is reported. This synthesis route improves key optical properties such as photoluminescence quantum yields and life times of excited states by inducing a controlled slow-down of the film formation and suppressing agglomeration effects. In situ spectroscopy reveals a delayed and slowed down crystallization process, which achieves synthesis of perovskite structures with much reduced defect densities. Further, aggregation can be controlled by the amount of amino acid added and adjusting the synthesis protocol allows to produce cubic crystallites with targeted size from nanometer to micrometer scales. The nanocrystalline MAPbBr3 samples show enhanced amplified spontaneous emission (ASE) intensities, reduced ASE thresholds and purer ASE signals, compared to pristine films, even under intense optical driving, making them promising structures for lasing applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 6","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202402441","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475478","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}

Benefiting from the efficient separation of photogenerated carriers under the type-II band alignment, the device exhibits remarkable self-powered characteristics, achieving a responsivity of 0.32 A/W and a quantum efficiency of 76% at zero bias under 532 nm laser illumination, with a specific detectivity of 6.15 × 1013 Jones. Notably, due to the interlayer transitions of photogenerated carriers, the operating wavelength range of the detector is extended to the telecommunication band (i.e., 1550 nm).

Owing to their excellent biocompatibility, ease of synthesis, good aqueous dispersion, high chemical stability, unique cross-linking structure, and modifiable surface properties, CPDs have attracted significant attention. However, pure CPDs exhibit certain limitations in terms of optical performance, particularly in terms of fluorescence intensity, phosphorescence intensity, and emission wavelength tunability, which may not meet the requirements of specific applications. To address these limitations, doping CPDs with various elements, such as nitrogen (N), sulfur (S), and phosphorus (P) to modify their band structure and surface functionalization can significantly enhance their optical properties and photochemical stability, thereby expanding their application potential. This paper reviews the main synthesis methods for elementally doped CPDs, examines the effects of different types of elemental doping on their photochemical properties, and explores promising applications in optoelectronic devices, sensors, and catalysis. Finally, recent advancements in elementally doped CPDs are summarized, along with future development directions and challenges.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 12","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861496","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, the rapid recombination of electron-hole pairs intrinsically significantly hinders the performance improvement of MoS2 photodetectors. Achieving carrier manipulation to suppress recombination is crucial and challenging for MoS2 photodetectors. Herein, we report three MoS2 photodetectors decorated with platinum single atoms (Pt SAs), platinum single-layer clusters (Pt SCs), and platinum nanoclusters (Pt NCs) via an impregnation method. Carrier recombination in MoS2 is suppressed by growing Pt SAs, Pt SCs, and Pt NCs. Furthermore, Pt SAs, Pt SCs, and Pt NCs have different effects on carrier behavior due to the size effect and disparate interactions with MoS2. Among the Pt SA/MoS2, Pt SC/MoS2, and Pt NC/MoS2 devices, Pt SC/MoS2 exhibits a responsivity (R) of 1.44 × 102 A W−1 and a specific detectivity (D*) of 1.07 × 1010 Jones under 532 nm illumination with a power density of 0.5 mW cm−2.
