An ultrafast photodetector that captures optical transients on nanosecond timescales, far surpassing the ≈µs speed limitations of conventional photosensors is presented. Achieving a 61 ns response time (33 ns halfwidth) via a coplanar Schottky-capacitive design, this device leverages instantaneous photo-induced capacitance modulation to generate transient current spikes, effectively bypassing RC time-constant limitations. The resulting transient detection mode offers a large linear dynamic range (>93 dB) and a 6000% enhanced sensitivity compared to conventional steady-state photocurrent operation. This ultrafast speed and sensitivity are harnessed for secure high-speed data transmission and logic processing via an electro-optical modulation scheme that ensures reliable, tamper-resistant information encoding. Furthermore, the photodetector's nonlinear, bias-tunable photoresponse captures distinct material-dependent optical signatures, allowing machine learning classification of metals, insulators, and semiconductors with over 82% accuracy. By integrating ultrafast optical detection with secure communication and logic processing capabilities, this photodetector platform represents a transformative solution for next-generation robotics, automation, intelligent sensing, and high-security materials characterization.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284946","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}

Herein, the example combining chiral carbon nanodots (cCND) and metal-organic framework (MOF) film is reported for achieving broadband excited CPL with UV–vis light excitation. The stable Zr-MOF containing perylene-based ligand with broadband excitation is prepared by using the vapor-assisted conversion method, and then is loaded with chiral precursors and microwave-treated to obtain cCND loaded MOF (cCND@MOF) films. The resulted host-guest film not only in situ encapsulates uniform sized cCND into MOF film with microwave treatment, but also avoids the aggregation-caused quenching effect of cCND and enhances the chiral/energy transfer from perylene based MOF film for achieving intense luminescence and high CPL with broadband excitation wavelengths from UV to visible region, and increased the glum to 10−2. This study provides an efficient and convenient microwave-assisted method for constructing host-guest materials by loading cCND into MOFs, and develops broadband excited CPL film materials.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284710","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}

MXene, as an emergent 2D material, exhibits excellent optothermal and mechanical properties when coated on various substrates. Herein, a novel optothermal manipulation platform based on multilayered MXene nanosheets is proposed, with great cell compatibility. The experimental and theoretical results demonstrate that individual multilayered MXene nanosheets exhibit superb photothermal conversion efficiency at visible wavelengths. The 500 nm-diameter colloidal particle can be stably trapped and transported under a power of 0.6 mW, which is over two orders of magnitude smaller than traditional optical tweezers. Specifically, a reversible self-assembly of colloidal particles with diverse patterns, including hexagonal crystallization, chain pattern, and ring-shaped assembly. This is realized by control over the laser-induced temperature gradient and thermophoretic response. Furthermore, a single-flake level MXene can also closely adhere to the cell membrane, in addition to glass substrates. This enables directed migration and assembly of a large number of particles on a cellular substrate. Compared with a typical noble metal substrate, MXene has better biocompatibility, flexibility, and without the need for complex micro-nano fabrication processes. It is expected to promote applications in biomolecular interactions, cellular drug delivery, and colloidal crystals.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284941","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}

Understanding and controlling chiroptical activity in such materials is crucial for advancing next-generation photonic and spintronic technologies. A widely held belief is that enantiopure systems inherently offer the strongest chiroptical responses. In this perspective, this assumption is questioned by drawing attention to nonlinear dependencies between normalized chiroptical response as given by the anisotropy factor, g, and enantiomeric excess (ee) in thin-film systems. Using 2D and 1D chiral hybrid metal-halide perovskites as testbeds, it is shown that the highest optical activity often emerges at intermediate ee values – far from the enantiopure limit. Also, for tryptophan (a chiral amino acid), a similar response is observed. This behavior points to complex structural reorganizations and interaction patterns in chiral films. The common practice of limiting chiroptical measurements on chiral films to racemic and enantiopure samples overlooks a rich, informative regime is believed. Systematic g–ee profiling is proposed as a standard part of the experimental workflow in chiral materials research, which can reveal underexplored material spaces and enable more deliberate control of chiroptical properties.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501895","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284889","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}

These devices have promising applications for hardware security, authentication, cryptographic key generation, and anti-counterfeiting measures across multiple industries. This review enlightens the diverse material platforms used for OPUFs, ranging from fiber optics and liquid crystals to advanced semiconductor nanocrystals and plasmonic metasurfaces, each offering distinct optical characteristics that impact security strength. While no single material system dominates the field, hybrid and multi-model approaches integrating low-dimensional materials are being explored to enhance reliability and scalability.
