Abstract Photothermoelectric (PTE) photodetectors with self-powered and uncooled advantages have attracted much interest due to the wide application prospects in military civilian fields. However, traditional PTE lack of mechanical flexibility cannot operate independently without test instrument. Herein, we present a flexible photodetector capable dual-mode output, combining electrical optical signal generation for enhanced functionality. Using solution processing, high-quality MXene thin films are assembled on asymmetric electrodes as photosensitive layer. The geometrically electrode design significantly enhances responsivity, achieving 0.33 mA W −1 under infrared illumination, twice that symmetrical configuration. This improvement stems from optimized photothermal conversion an expanded temperature gradient. device maintains stable performance after 300 bending cycles, demonstrating excellent flexibility. A new energy pathway has been established by coupling thermochromic composite materials, leading real-time visualization invisible radiation. Leveraging this functionality, demonstrate first human–machine collaborative imaging system, wherein arrays synchronously generate human-readable pattern machine-readable pattern. Our study not only provides functional integration photodetectors, but also sets benchmark optoelectronics.

Abstract The conventional Lewis acid molten salt etching approach for synthesizing MXenes typically necessitates elevated temperatures exceeding 550 °C, in addition to the use of inert gas protection prevent oxidation. Additionally, delamination salt‐etched requires hazardous intercalating agents. Herein, a scalable and non‐toxic low‐temperature shielded (LSS) MXene air is reported, with only small portion salts low reaction temperature down 150 °C. Especially, synergistic effect increased diffusion rate by Li + ions phase change magnesium chloride hexahydrate (MgCl 2 ·6H O) enables redox‐controlled A‐site parent MAX phase, which even facilitates synthesis hard‐to‐etch MXenes. As proof‐of‐concept demonstration, several theoretically hard‐to‐synthesize including Cr CT x Nb are successfully prepared through LSS technique, where not achieved acidic yet. Compared techniques, this method exhibits unconventional behavior while offering advantages, non‐oxidizing environment, shorter processing time, elimination highly corrosive washing agents organic intercalants. These advances render promising route applications toward diverse practical applications.
