At the nanoscale, they have attracted considerable interest for applications in in vivo imaging, photodynamic therapy, and biosensing. In 2023, an unexpected phenomenon was reported: a dose-dependent enhancement of PersL in ZnGa2O4:Cr3+ nanoparticles (ZGO:Cr3+ NPs) upon exposure to hydrogen peroxide (H2O2), opening a novel in vitro strategy for biomolecule detection. This strategy allows for fast and sensitive qualitative and quantitative detection of H2O2 that is of major diagnostic relevance as it results from enzymatic processes and serves as a key biomarker in a wide range of diseases. This study investigates the fundamental mechanism underlying H2O2-induced PersL enhancement in ZGO:Cr3+ NPs using a combination of structural, optical, photochemical, and surface chemistry analyses. It is demonstrated that under UV-C irradiation, ZGO:Cr3+ NPs produce photoelectrons initiating a redox reaction with adsorbed H2O2. Produced hydroxyl radicals (•OH) interact with the nanoparticle surface to generate additional charge carriers, ultimately intensifying and prolonging Cr3+ luminescence. These results reveal a previously unknown charging pathway in persistent phosphors, combining photocatalysis and chemiluminescence, and lay the foundations for advanced applications in biodetection and other emerging photonics technologies.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 12","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202502409","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147565090","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}

Moreover, an equally crucial challenge remains: efficiently extracting and transporting trace amounts of target chemical or biological molecules from their highly diluted solutions to the tiny SERS hot spots. This issue remains unresolved and continues to hinder the widespread application of SERS for molecular sensing.

Introducing porosity into these structures is a promising route to enhance environmental and surface sensitivity, yet realizing deeply subwavelength porosity through conventional top-down fabrication remains challenging due to limitations in achieving high aspect ratio nanoscale features. Here, mesoporous silicon metasurfaces (pSi-MSs) supporting Fano guided-mode resonances are reported, realized via a straightforward hybrid top-down patterning and bottom-up porosification approach. The resulting structures exhibit tunable resonances across the visible spectrum, vivid structural coloration, and dynamic color changes in response to environmental stimuli, including vapor and liquid interactions. By integrating laser illumination, colorimetric contrast for real-time detection is further enhanced. Finally, label-free refractive index sensing and real-time small molecule detection are demonstrated using an integrated differential sensing design with microfluidic pSi-MSs. These results establish the pSi-MS as a versatile platform for responsive photonic devices, dynamic color modulation, and surface-based chemical and biological sensing.

Despite promising applications in dynamic anti-counterfeiting, information encryption, and smart optoelectronic devices, these materials often suffer from limited emission color changes, insufficient color diversity, and short phosphorescence lifetime. To overcome these limitations, we present an innovative molecular engineering strategy that unites two phosphorescent components with distinct emission colors, lifetimes, and thermal sensitivities in a single polymer backbone, achieving multicolor and temperature-controllable phosphorescence. Specifically, a series of pyrene-1-carboxylic acid (PyCA) end-functionalized PA69 polymers with precisely controlled PyCA contents is synthesized. The flexible PA69 chains generate long-lived yellow-green phosphorescence strongly modulated by temperature, while the rigid π-conjugated pyrene emits relatively short-lived red phosphorescence with excellent thermal stability. Upon increasing temperature, the distinct thermal quenching rates of these two emissive centers lead to a continuous color transition from yellow-green to red. Remarkably, Py-PA69 retains second-scale afterglow even at 348 K. Py-PA69 also exhibits component-dependent and time-dependent phosphorescent properties. This programmable luminescence enables advanced applications, including time-dependent multicolor anti-counterfeiting patterns, time-gated four-dimensional (4D) encryption codes, temperature-responsive digital displays, and emergency signage with thermally indicative luminescence.\u0000 </div>","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 12","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147563305","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}

In this work, we investigate a series of lanthanide molecular complexes with a highly rigid tetrapodal benzimidazolic ligand (L) as potential highly coherent quantum light sources suitable for on-chip integration. The LnL complexes show sensitized Ln-centered emission in the visible and near-infrared spectral ranges with a well-resolved fine structure of the J sublevels. Remarkably, the EuL complex exhibits a single line related to the purely electric dipole 5D0→7F0 transition, of particular interest in quantum photonics. Notably, this formally forbidden line likely originates from an LMCT state, rather than from low symmetry or strong crystal-field effects. This mechanism enables the appearance of the band while maintaining a limited electric inhomogeneity of the ligand system, as supported by Judd–Ofelt analysis. These features contribute to the significant reduction of the room-temperature inhomogeneous linewidth (∼500 GHz) compared to typical zero-phonon lines of polyaromatic molecules in polymers.
