Non-fullerene acceptors (NFAs), such as ITIC and Y6, significantly propel photovoltaic performance due to their strong absorption and steep band edges. The frontier orbitals of ITIC and Y6 mainly distribute on central conjugated backbones while little on electron donor and terminal acceptor segments, indicating a more localized electronic signature rather than a charge transfer state. The single crystal structures of ITIC and Y6 indicate that the π-conjugated backbones appear homogeneous carbon-carbon bond lengths, and the calculated atomic charge distribution demonstrates that the carbon atoms of π-conjugated backbones carry alternating positive and negative partial charges, revealing soliton-like electronic structural characteristics in these molecules. Inspired by cyanine dyes, these soliton-like features are considered to be the origin of ITIC and Y6 strong and tailless absorption spectra. Further analysis shows that the introduction of an acceptor group (benzothiadiazole) induces more extensive soliton waves in the conjugated backbones (Y6) compared to ITIC, resulting in stronger absorption and steeper band edge. The analysis suggests that soliton-type NFA materials are expected to provide new insight for designing high-performance organic photovoltaic materials.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 10","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770593","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 development of efficient devices is currently hampered by the lack of suitable NIR-emissive materials. Achieving this goal is even more challenging when the use of non-toxic, earth-abundant metal complexes as electroactive materials is targeted. Herein, an enlarge family of binuclear Cu(I) emitters (D1–D4) bearing the bridging thiazolo[5,4-d]thiazole scaffold is described along with their mononuclear counterparts (M3–M4), which are synthetized and characterized comprehensively by a combination of chemical, spectroscopical, electrochemical and computational techniques. By means of an efficient dinuclearisation strategy in combination with the selective tuning of the π-accepting feature of the lateral N-heterocyclic rings enabled modulation of photo- and electro-luminescence spectra into the NIR-I region. Light-emitting electrochemical cells (LECs) fabricated by employing the binuclear copper complexes displayed electroluminescence into the deep-red to NIR-I region. Remarkably, derivative D2 shows the combination of λEL,max up to 782 with a spectral profile squarely falling into the NIR region, excellent carrier balance and good EL performances among all types of emissive materials used for NIR LECs.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 8","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622590","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 method ensures both sensitive and specific glucose detection by exploiting the enhanced luminescence of PLNPs in the presence of H2O2, generated by an enzymatic reaction. To this end, three different PLNPs composed of ZnGa2O4:Cr3+ (ZGO) nanoparticles are prepared by hydrothermal synthesis at 120 °C for 6 h (ZGO1), 12 h (ZGO2), and 24 h (ZGO3), followed by a calcination at 500 °C, resulting in nanoparticles with an average hydrodynamic diameter of 100 nm ± 5 nm after grinding and centrifugation. These nanoparticles are efficiently covalently functionalized with GOx, via a PEG linker. Following the production of H2O2 by the enzymatic reaction between GOx bound to the ZGO surface and glucose present in 100-fold diluted serum, a significant increase in the persistent luminescent signal is observed. This phenomenon is most pronounced for ZGO2, for which a detection limit of 0.01 µm and a detection range from 0.05 to 1 µm is obtained.

Understanding the mechanisms governing plasmonic effects is crucial for optimizing the yield and selectivity in plasmonic catalysis. However, challenges persist in elucidating the role of plasmonic field effects due to the complex interactions among various contributing mechanisms. This study introduces Au@Al2O3-Pd-Au@Al2O3 trimer arrays to decouple plasmonic field effects from other influences. The alumina coating on the Au particles prevents charge transfer between gold and reactants, enabling focused examination of the field effects on Pd catalysts. Employing real-time monitoring with liquid-state surface-enhanced Raman scattering (SERS), this work investigates the catalytic efficiency and kinetics of the C─C coupling reactions on palladium by tuning the near-field strengths. Polarization-dependent studies reveal that strong near-field intensity around the trimer structures is amplified by ≈60-fold under optimized conditions. The findings offer insights for optimizing catalytic reaction conditions and designing more effective composite plasmonic catalysts.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 10","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770556","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, it is impeded in practical applications by its specific high-energy laser source. Herein, a white-light responsive Ce3+-mediated toroidal energy migration downshifting topological core–shell structure NIR-IIb (1500–1700 nm) fluorescent probe is reported. It is found that Ce3+ doping enhances the NIR downshifting luminescence of the Ho3+ and Nd3+, thereby increasing the energy-transferred Yb3+ luminescence. The NaCeF4 core is able to further facilitate the crossrelaxation between the intermediate-shell layer of Er3+ and Ce3+ through the outward-to-inward core–shell topology, enhancing the 1527 nm luminescence to form the toroidal energy migration paradigm. Additionally, the luminescence of Er3⁺ exhibits strong temperature dependence, enabling superior temperature sensing under multiple light sources. Under low-power white light source, the relative sensitivity (Sr) can reach up to 0.57% K−1, with a minimum temperature uncertainty (δT) of 0.2 K. Moreover, portable light conversion using highly efficient white-light responsive emission in NIR-II region enables noninjectable intravenous imaging and food inspection.

The optical Kerr effect, a third-order nonlinear phenomenon, causes anisotropic changes in the refractive index of materials under intense laser illumination. However, this effect is intrinsically weak, limiting its utility in free-space nanophotonics. This work demonstrates an enhancement of the optical Kerr effect by over three orders of magnitude through guided-mode resonance in a dielectric diffraction grating with a thickness of less than 300 nm. The study includes the design, fabrication, and transmittance measurements of a resonant silicon nitride crossed grating, illuminated with short light pulses. Spectral resonance shifts with increasing pulse power are observed, resulting in over 50% modulation of the resonance magnitude and enabling dynamic transitions between “Off ” and “On” transmission states of the grating. Additionally, the potential of the grating for dynamic pulse shaping is demonstrated.

In 3TPA-CyDOBNA, three electron-rich triphenylamine (TPA) units are positioned on the central benzene ring of CyDOBNA to maximize distortion from an acceptor plane. This modification reduces the singlet–triplet energy gap (ΔEST) by 0.16 eV, highlighting its thermally activated delayed fluorescence (TADF) characteristics. However, congested TPA donors on the bottom side of the central benzene are found to facilitate non-radiative decay in a triplet state, indicating that ΔEST alone is insufficient for optimal device performance. Further refinement led to the creation of Ph2TPA-CyDOBNA, where two TPA donors and one phenyl group are positioned side by side to minimize non-radiative pathways while preserving the TADF behavior. This results in a reverse intersystem crossing rate of 2.30 × 105 s−1 and ΔEST of 0.15 eV. Photophysical investigations reveal that these emitters exhibit not only TADF but also aggregation-induced emission properties, maintaining a high photoluminescence quantum yield (PLQY) even in the solid state. In a doped OLED device, an external quantum efficiency (EQE) of 18.9% is achieved for 3TPA-CyDOBNA. Compared with 3TPA-CyDOBNA, the EQE of Ph2TPA-CyDOBNA improves by 21.1%, primarily because of the suppression of excessive flexibility from the three TPA donors.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 9","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689126","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, this perspective is slowed down by toxicity concerns, the most effective materials being based on Pb and Hg. There is currently a large effort to bring forth new platforms that are active in the infrared with a reduced heavy metal content. Here, the focus is on silver chalcogenides, which, thanks to a combination of inter- and intraband transitions, is suited to cover both short and mid wave infrared ranges. However, this material being less mature, the achieved photoluminescence (PL) appears quite broad, which is problematic for device integration. Here, it is demonstrated that a strong control over the PL spectrum can be obtained through integration into a dielectric cavity that magnifies the electric field by a factor 20 and narrows the PL full width at half maximum down to 15 nm for an emission at telecom wavelength. The PL is also highly directional to avoid most waveguiding effects which is of utmost interest for enhancing the efficiency of NC-based light emitting diodes.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 10","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770555","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}
