However, the conventional fabrication methods can only provide porous metal resonators less degree-of-freedom in morphology, significantly limiting their optical properties. This work proposes a porous bimetallic nanopillar array biosensing platform, the nanoporous gold pillar (NPGP), enabled by a hybrid porosity-on-nanoarray nanofabrication method. NPGP achieves spectral tunability by setting the main resonance through the morphology of nanopillar-supported transition gold inner core while expanding the resonance spectra through the nanoporous gold outer crust. The capability of NPGP as an on-chip fluorescence sensing platform is demonstrated in the detection of soybean stay-green associated geminivirus (SoSGV). With trace amounts of virus in ground leaf buffer solutions, the porous metal morphology captures the virus with high efficacy. Combined with the high field-strength region of NPGP, a fluorescence enhancement two orders of magnitude higher than that of a gold plane is achieved. This work has provided a new hybrid nanofabrication method and nanoporous plasmonic architecture that can create highly tunable porous optical resonating devices for wide use in biological and chemical molecule detections.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284879","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}

Most of the polymorphic crystal phases of this semiconductor belong to the family of 2D van der Waals semiconductors. In this study, optically active indium selenide crystal phase heterostructures are fabricated by molecular beam epitaxy in a well-controlled manner. It is demonstrated that by changing the growth conditions one may obtain either γ-InSe, or γ-In2Se3, or β-In2Se3 crystal phases. The most promising crystal phase heterostructures from the point of view of photonic applications is found to be the γ-InSe/γ-In2Se3 heterostructure. An intense optical emission from this heterostructure appears in the near infrared spectral range. The emission energy can be tuned over 250 meV by changing γ-InSe layer thickness, which is explained by the quantum size effect. The optically active indium selenide crystal phase heterostructures represent, therefore, an interesting platform for the design of light sources and detectors in the near infra-red.

The metasurface is fabricated through a microsphere-assisted deposition and etching strategy, yielding highly ordered nanostructures with strong vertical field confinement. Simulated and experimental reflectance spectra confirm that the hybrid architecture supports multiple localized surface plasmon resonance (LSPR) modes—absent in the individual components—originating from enhanced near-field coupling between the AgNDs and AuNWs. A comprehensive analysis reveals that geometric parameters such as nanodisc radius and nanowire height significantly affect the spectral response and field distribution. The sensor achieves a maximum refractive index (RI) sensitivity of 611.47 nm/RIU and a humidity sensitivity of 0.858 nm/%RH when coated with a polyvinyl alcohol (PVA) layer. Furthermore, dynamic spectral tuning is realized by selectively etching the alumina template to modulate the effective refractive index of the supporting substrate.

The design of VPCs is typically based on analogies with condensed-matter topological insulators that exhibit the quantum valley Hall effect; trial-and-error approaches are often used to tailor the photonic band structures and their topological properties, which are characterized by the local Berry curvatures. In this paper, an inverse design framework based on frequency-domain analysis is presented for VPCs with arbitrary pseudospin states. Specifically, the transverse spin angular momentum (TSAM) at the band edge is utilized to formulate the objective function for engineering the desired topological properties. Numerical experiments demonstrate that the proposed design approach can successfully produce photonic crystal waveguides exhibiting dual-band operation, enabling frequency-dependent light routing. The pseudospin-engineering method thus provides a cost-effective alternative for designing topological photonic waveguides, offering novel functionalities.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 27","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145110947","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 review categorizes and analyzes structural modifications across four key molecular architectures—pristine QAOs, phenyl-substituted QAOs, cyclized QAOs, and polynuclear QAOs—revealing their distinct impacts on full width at half maximum (FWHM), reorganization energy (λ), and excited-state dynamics. Notably, structural strategies such as R1 substitution, R4-R5 cyclization, and steric shielding with bulky groups like tert-butyl lead to enh anced molecular rigidity, suppressed vibrational relaxation, and record-narrow emissions (FWHM ≤ 13 nm). Furthermore, donor-acceptor tuning across the series enables precise the highest occupied molecular orbital (HOMO) – the lowest unoccupied molecular orbital (LUMO) separation, balancing short-range charge transfer with emission color control. Emission statistics, fluorescence lifetime analysis, and device performance metrics are presented, consolidating structure-property relationships across >100 reported derivatives.

Metal–organic frameworks (MOFs) provide a promising platform to address these challenges due to their highly tunable structure and customizable modularity. Herein, a modular engineering strategy is proposed and develop a programmable assembly platform based on a series of Ln-MOFs with identical topology structures. Through rational energy level engineering, the obtained Ln-MOFs scintillators exhibit intense X-ray excited luminescence, high relative light yield, perfect linear response to X-ray dose rate, and excellent stability. The fabricated MOF-based scintillating membranes demonstrate promising potential in flexible X-ray imaging with high spatial resolution. Some fundamental design principles are elucidated through investigating systematic correlation of scintillating performance with energy levels, luminescent efficiency, and self-absorption effects.
