However, achieving adjustable MML within a unified material framework is challenging due to the distinct responses of different luminescence modes to a common external stimulus. In the work, a novel approach is devised for regulating the aggregation or dispersion state of carbon dots (CDs) to exhibit responsive MML, including fluorescence (FL), room temperature phosphorescence (RTP), and chemiluminescence (CL). Specifically, aggregation-caused luminescence quenching CDs (ACQCDs) are synthesized via a one-step hydrothermal method using levofloxacin. These ACQCDs exhibit ACQ and significant aggregation-induced color change effects. When ACQCDs interact with paper-based materials, they form hydrogen bonds, establishing a high-density hydrogen bond network that induces ACQCDs aggregation. Upon external stimulation, the hydrogen bond network undergoes dynamic changes, triggering ACQCDs dispersion. This process effectively deactivates nonradiative defect centers, stabilizes triplet excitons, and promotes simultaneous MML of tunable FL, RTP, and CL. The integration of multimodal luminescence with external stimulus input enables the creation of a programmable multi-input logic gate, offering significant potential for encoded information anti-counterfeiting applications. Overall, this research provides valuable insights into the conduction of MML CDs, thereby advancing the utilization of nanomaterials in intelligent encryption and anti-counterfeiting technologies. The findings pave the way for the development of more sophisticated and secure anti-counterfeiting measures based on the unique luminescent properties of CDs.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 5","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143397192","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}

An inverse excitation-dependent emission phenomenon and emission enhancement are observed in these two perovskites, attributed to the contraction of inhomogeneously coordinated [PbX6]4− octahedra. Pressure-induced lattice contraction promotes the overlap of Pb and X orbitals, resulting in a decrease in the bandgap. Concurrently, pressure-induced phase transitions, due to the distortion of [PbX6]4− octahedra, lead to discontinuous decreases in the bandgap.

In this work, a cascaded metadevice is constructed by integrating liquid crystal (LC) into a dielectric metasurface, and then the phase of each meta-atom is designed to achieve different polarization conversions and spatial phase gradient distributions. Therefore, by changing the polarization of the incident wave or the LC optical axis orientation, an active THz beam deflection device that can actively and independently control the spin state and deflection angle of the output wave can be obtained. Specifically, the output right circularly polarized (RCP) wave is deflected to the +1st diffraction order, and the output left circularly polarized (LCP) wave is deflected to the +2nd diffraction order. The experimental results indicate that the cascaded metadevice exhibits a large angular spatial dispersion in the frequency angle scanning range of +25°–+17.5° (+1st order) and +52.5°–+35° (+2nd order) corresponding to the broadband range of 0.6–0.83 THz. The spin isolation of all diffraction order channels can reach over 10 dB and the maximum diffraction efficiency of 56% can be obtained. In addition, the universality of the proposed LC-cascaded metasurface design concept has also been verified, providing a feasible path for complex, multifunctional, and active THz wavefront manipulation, thereby exploring more possible application scenarios.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 2","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120898","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 still remains formidable challenges to combine these two strategies in a single luminescent material. Here, it has integrated multiple-node time-gated information encryption and self-erased decryption data with transient imaging feature for enormously enhancing the information security protection based on the dynamic assembling/disassembling process of luminescence copper nanoclusters (CuNCs). Multiple CuNCs-based assemblies for the information encryption are controlled after introducing metal ions (Zn2+ and Al3+) and ammonia, which gives rise to the tremendously fluorescence improvement of CuNCs through aggregation-induced emission (AIE) effect. These assemblies can be disassembled upon adding a chelator agent (EDTA) in concomitant with fluorescence vanishing behavior. Their decomposition rates heavily depend on the type of metal ions, ammonia concentration, and EDTA concentration. Based on the dynamic disassembling process, time-dependent multi-node information is encrypted. The real information can be read observed only once at the correct “time key” and then automatically self-destructed within dozens of minutes.

However, some aggregates of phosphors will appear due to their limited solubility and phase separation in polymer matrix, resulting in unstable and/or poor RTP property. In this work, a new strategy, the utilization of cyclodextrins with fit cavity size, is proposed to improve the dispersion of phosphors and enhance RTP performance both in covalent and ionic bond system. The resultant high Förster resonance energy transfer (FRET) efficiency (ΦFRET) and outstanding RTP performance confirmed that the added cyclodextrins can effectively disperse fluorescence dye (guest) in covalently modified sodium alginate (SA-R) matrix. Thanks to the introduced “ FRET ruler”, the distance between energy donor and acceptor can be measured, accompanying with the afterglow color of SA-R films changing from green to red. For SA-NpC@RhB, the introduction of β-CD can enhance the ΦFRET up to 57.4%, with corresponding photoluminescence quantum yield (ΦPL) as high as 21.15%. The ΦFRET for SA-NpC/γ-CD@SR101 is ≈8.5 times enhanced, with the corresponding ΦPL rising from 0.87% to 19.13%. Besides, this strategy is also successfully applied into ionic bond system (SA/R), and the ΦPL for SA/BDA/γ-CD@RhB can reach 24.05%. Furthermore, these materials with good RTP performance are applied in multiple information encryption, optical information storage, and anti-counterfeiting.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 3","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120662","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 Cd-doped IGZO layer is fabricated in situ by a one-step microwave-assisted sol–gel process with reduced temperature (<125 °C) and time (<15 min). Despite the wide bandgap of the IGZO (≈3.83 eV) channel, visible-light (≈2 eV) photosensing is achieved in the developed phototransistor upon Cd doping owing to the reduced bandgap (≈3.71 eV) and increased density of subgap states associated with oxygen vacancies in the metal–oxygen bonding structure. In addition, the Cd-doped IGZO phototransistor exhibits excellent operational stability (up to 10 000 cycles) and long-term reliability (up to 30 days). Finally, the embedded Joule heater, based on the inherent transparent ITO substrate, significantly improves the recovery characteristics of the IGZO phototransistor owing to relaxation of the photoexcited charges at the oxygen-vacancy-related trap states upon heating, resulting in 100% recovery in a significantly reduced timeframe (≈10 s). These findings pave the way for the development of high-performance, stable, and reliable visible-light phototransistors based on wide-bandgap IGZO active sensing channels with fast and full recovery, expanding their practical applicability of optoelectronics.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 6","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475853","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}
