In this study, the influence of minor morphological variations by truncation of different planes on the plasmonic response of colloidal Au nanocube dimers and their separation (nanogap) is investigated by electron energy loss spectroscopy (EELS). To understand the impact of these factors, two different cube models for numerical simulations have been considered: one mimicking the truncation by {111} facets, and another mimicking their truncation by {110} ones. The experimental results, supported by numerical simulations, reveal two origins for the sensitivity of EELS spectra to nanostructure truncation: the plasmonic modes' dependence on facet geometry at the nanogap between Au nanocubes and the beam position's precision, which governs excitation efficiency. Notably, the nanogap distances between Au nanocubes are accurately measured using edge spread functions from High-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) images, demonstrating that STEM mode provides superior precision compared to the more commonly used TEM modes. These findings contribute to a deeper understanding of the relationship between structural features and plasmonic behavior in Au nanocube dimers, crucial for the designing next-generation plasmonic devices, including quantum plasmonic systems and SERS-based sensors.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 15","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202500042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148524","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}

Weaving electroluminescent fibers into textiles with designed patterns has proven as an efficient strategy to realize informative displaying. However, the design of multicolor electroluminescent fibers with a wide color gamut remains challenging for full-color display in electronic textiles. Herein, a multicolor electroluminescent fiber with high color purity has been proposed by incorporating light-conversion perovskite quantum dots with copper doped zinc sulfide (ZnS:Cu) electroluminescent layer. The color conversion of ZnS:Cu luminescent powder is facilitated through the narrow emission of perovskite quantum dots. The resultant luminescent fibers can emit a wide range of colors from blue, and green to red by varying halide compositions of perovskite quantum dots. The full width at half maximum of the emission peak is 23–37 nm, and the color gamut is increased to 102% of the National Television Standards Committee (NTSC) standard, which is superior to that of reported electroluminescent fibers. Such luminescent fibers can be manufactured at large scale with good reproducibility through a sequential solution deposition process. The luminescence remains stable and uniform after 10 000 cycles of bending and long-term storage up to 90 days. These luminescent fibers are readily woven or embroidered into electronic textiles for colorful information displaying.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 15","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148423","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}

Conjugated polymer extraction (CPE) can be used to achieve this goal. However, the obtained purified SWCNTs are often very diluted, hindering their use. Furthermore, the SWCNTs prepared this way often exhibit unsatisfactory photoluminescence quantum yields (PLQYs). In this study, how both of these problems can be solved by the application of a newly designed platform is shown for differentiation/covalent modification of SWCNTs. The addition of organic phenylhydrazine derivatives is found to greatly increase the yield of SWCNT separation. Concomitantly, such a range of chemical compounds also revealed great utility for the introduction of luminescent defects into SWCNTs to enhance PLQYs. The density of defects can be tailored by various parameters, while the duration of the process is dramatically shorter (tens of seconds to minutes) than that of the well-known methods (several hours to days). Notably, the described SWCNT functionalization framework modifies SWCNTs very effectively both in organic solvents and water (at a reactant concentration of ≈ 100 ng mL−1). The straightforward nature of the reported approach and its high versatility open the way toward a broad spectrum of long-awaited applications of monochiral SWCNTs.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 12","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861564","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}

To enable a broader tailoring of polariton properties, it is important to develop means to better control molecular orientation and tune the intensity of the exciton–photon interaction. Vapor-processed, glassy organic thin films are previously shown to have tunable molecular orientation as evidenced by phenomena including birefringence and transition dipole moment (TDM) alignment. Here, this tunability in TDM orientation with thin film processing conditions is exploited to continuously vary the interaction between the exciton and confined cavity photon mode. By embedding a thin film of 4,4′-bis[(N-carbazole)styryl]biphenyl (BSB-Cz) in a metal-reflector microcavity, ultrastrong coupling and hybridization of multiple electronic transitions of BSB-Cz are demonstrated with a common cavity mode. Increasing the temperature during BSB-Cz deposition tunes the TDM orientation from predominantly in-plane to random to slightly vertical. This leads to a corresponding ≈30% variation in the associated Rabi splitting, consistent with theoretical predictions. This work demonstrates a means to continuously tune coupling strength from a materials perspective while also providing a handle to tune orientation disorder in thin film.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 12","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202403135","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861566","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}

It may significantly benefit a broad range of applications, including infrared light sources, radiation detection, and waste heat utilization of thermophotovoltaics. However, existing thermal emitters face challenges in realizing narrowband and directional emissivity and lack independent control of angular and spectral selectivity. This study develops a simple but novel approach to thermal emitter design that enables independent control of directionality and emissivity peak of thermal radiation. An angle-selective filter and a spectral selective emitter are selected as the structural components, and a series of different narrowband and directional thermal emitters are designed to show the advantage of independent tunability. After optimization with the NSGA-II algorithm, a narrowband and directional thermal emitter is achieved, offering high emissivity only at the given direction and wavelength. An emitter with only seven layers demonstrates a maximum emissivity of 0.97, an angular width under 20°, and a spectral width below 0.025 µm, as validated by angle-resolved emissivity measurements. This study provides a straightforward and effective route for designing narrowband and directional thermal emitters with promising applications in thermal radiation management.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 12","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861565","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}
