ZnO nanomaterial-based UV photodetectors (UV PDs) have a long response time and poor responsiveness. The adjustable work function high conductivity of 2D Ti3C2-MXene make it suitable electrode material for optoelectronic devices. In this work, the MXene/ZnO nanorods Schottky junction hybrid was constructed via spin-coating nanosheets deposited on 1D array, increasing optical absorbance range. PD at 368 nm 5 V bias performs noticeably better with on/off ratio 806, responsivity 142.2 mA W–1, specific detectivity 2.03 × 1010 jones, which are, respectively, increased by 14.4, 418, 4194 times than pure PD,. particular, rise fall are 12.2 s/3.9 s, 31 76% faster those PD, respectively. Developing PDs provides an alternative strategy to improve rate photoelectrical properties over conventional alloy solutions.

Fiber-shaped photodetectors (FPDs) with multidirectional light absorption properties offer exciting opportunities for intelligent optoelectronic textiles. However, achieving FPDs capable of working in ampule environments, especially high sensitivity, remains a fundamental challenge. Here, quasi-solid-state twisted-fiber photoelectrochemical (FPPDs) consisting photoanode, gel electrolyte, and counter electrode are successfully assembled. In situ decorated n-type one-dimensional (1D) TiO2 nanowire arrays 2D Ni-Fe metal-organic framework (NiFeMOF) nanosheets serve as hierarchical heterojunction photoanodes, thereby optimizing carrier transfer dynamics at the photoanode/electrolyte interface. As expected, resulting self-powered FPPD exhibits 88.6 mA W-1 responsiveness < 30 ms fast response time. Significantly, our can operate both terrestrial aquatic environments thanks to its intrinsic ionic properties, making it versatile tool detecting ultraviolet on land facilitating optical communication underwater.

Fiber-shaped photodetectors (FPDs) have attracted special attention to wearable health monitoring due their 3D absorption capabilities. However, the practical application of traditional FPDs is severely limited by irreversible degradation performance caused vulnerable interface compatibility on complex deformation and a single function. Here, an integrated photoelectrochemical FPD/battery device (FPDB) designed, consisting common electrode, photoanode, anode, sol-gel electrolyte as isolation layer, which not only effectively avoids short circuit problem FPD but also endows high-efficiency energy storage capacity. As expected, resulting all-in-one triple-twisted fiber-shaped FPDB simultaneously achieves high responsiveness 151.45 mA W-1 excellent volume capacity 18.75 mAh cm-3. Such stable architectural design multifunctional integration functional fibers accelerate development next-generation fabrics.

This study demonstrates the development of an ultraviolet (UV)‐C photodetector (PD) fabricated using a surface‐passivated SnO 2 thin film deposited via spray pyrolysis.

Furthermore, even when subjected to modest UV light intensity 6 μW cm −2 , device shows significantly high responsivity 1500 A W −1 external quantum efficiency 7 × 10 5 %, detectivity 13 Jones. When compared previously reported ‐based PDs, this exhibits consistent performance over long working time, which may be due suppression surface vacancy defects passivation, as observed from structural optical measurements. type PDs has potential useful in wide range applications, including industrial sensing, medical diagnostics, environmental monitoring.

Abstract The unity of high‐stability and high‐performance in two‐dimensional (2D) material devices has consistently posed a fundamental challenge. Halide perovskites have shown exceptional optoelectronic properties but poor stability. Conversely, oxide exhibit stability, yet hardly achieve their high photoelectric performances. Herein, for the first time, 2D perovskite LaNb 2 O 7 (LNO) is engineered wide‐temperature UV light detection human motion detection. High‐quality LNO nanosheets are prepared by solid‐state calcination liquid‐phase exfoliation technique, resulting stability against temperature, acid, alkali solutions. As expected, individual nanosheet device achieves ultra‐wide temperature (80–780 K) ultra‐high (3.7 × 10 4 A W −1 at 780 Importantly, it shows responsivity (171 ), extraordinary detectivity (4 12 Jones), fast speed (0.3/97 ms), long‐term under ambient conditions. In addition, wafer‐scale film can be used as pixel array detectors imaging, large‐area flexible satisfactory photodetection performance after repeated bending tests. Interestingly, also distinct piezoelectric characteristics, which serve high‐sensitivity stress sensors These encouraging results may pave way more innovative advances materials diverse applications. image
