The work function of MXenes can be largely adjusted to approach 600 meV through simple incorporation of V₂O₅ via a charge transfer doping mechanism. Exploiting this strategy, the performance of MXene/GaN heterostructure-based deep ultraviolet (DUV) photodetectors has been greatly improved. Specifically, the photocurrent is enhanced by nearly 3 times, and the dark current is suppressed at the lowest order of magnitude, resulting in improved responsivity and specific detectivity of 121.6 mA/W and 2.23×10¹³ Jones, respectively, at 265 nm. The device also displays an ultralow dark current of 10⁻¹⁴ A, a fast response speed of 0.4 ms/15.1 ms, a large linear dynamic range exceeding 150 dB, and a high DUV/near ultraviolet rejection ratio of 2.41×10⁵. Owing to its good device performance, the detector is capable of sensing weak photon signals produced by a fire flame and functions as an optical receiver to transmit a text signal in a DUV light communication system. The proposed MXene doping method is expected to help develop MXene-based electronic/optoelectronic devices, and the present DUV photodetectors will find potential applications in DUV optoelectronic systems.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":773,"journal":{"name":"Science China Materials","volume":"68 4","pages":"1012 - 1021"},"PeriodicalIF":6.8,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716689","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 review, the strategies adopted for fabricating supramolecular fluorescent materials and their corresponding anticounterfeiting technologies have been discussed. Especially, the time-dependent luminescent materials, which were created by non-equilibrium supramolecular assemblies and exhibited significant changes in fluorescence intensity and wavelength over time, were highlighted for their unique dynamic feature.
