Article Abstract
Herein, FePS/reduced graphene oxide heterostructure has been prepared via a typical hydrothermal process, and flexible photodetectors based on hybrids have been subsequently fabricated. The photoresponse measurement results demonstrate that the photodetector exhibits obvious photoelectric conversion behavior without applied potential, indicating that the device possesses the capability to be self-powered. In addition, the photocurrent density of the as-fabricated photodetectors reaches up to 125 nA cmunder 90 mW cmillumination intensity without an external power source, which is 5.86 times higher than single FePS-based devices. Furthermore, the maximum attenuation in photocurrent density of the as-fabricated flexible photodetectors measured at -0.3 V after different bending cycles and bending angles is 29.8% and 17.7%, respectively. These results demonstrate that the as-fabricated photodetectors have excellent flexibility and provide a simple and effective strategy for the construction of flexible photodetectors.

Superlinear photodetectors hold significant potential in intelligent optical detection systems, such as near-field imaging. However, their current realization imposes stringent requirements on photosensitive materials, thereby limiting the flexibility of the device integration for practical applications. Herein, a tunable superlinear GaO deep-ultraviolet gate-all-around (GAA) phototransistor based on a p-n heterojunction has been proposed.

The exponential growth of data in the information era has pushed conventional optical communication technology to its limitations, including inefficient spectral utilization, slow data rate, and inherent security vulnerabilities. Here, a transformative high-speed organic spectral wireless communication (SWC) technology enabled by a flexible, miniaturized, and high-performance organic hyperspectrometer is proposed that integrates ultrahigh-speed data transmission with hardware-level encryption. By synergistically combining organic photodetector arrays with tunable responsivities and spectral-tunable organic filters, the organic hyperspectrometer achieves a broad spectral detection range of 400 to 900 nm, resolution of 1.

Near-infrared (NIR) detectors, serving as critical technological nodes bridging microscopic molecular recognition and macroscopic intelligent perception, meet the demands of cutting-edge technologies such as multispectral imaging. Organic semiconductor materials demonstrate unique advantages for NIR organic photodetectors (OPDs) due to their precisely tunable bandgaps, solution processability, flexibility compatibility, and biocompatibility. However, the narrow-bandgap intrinsic characteristics required for NIR response inevitably lead to carrier concentration surge that exponentially increases dark current, while hot carriers undergo phonon scattering relaxation that suppresses carrier collection.

Photoelectrochemical (PEC) sensors have garnered increasing attention due to their high sensitivity, low background signal, and rapid response. The incorporation of hydrogels into PEC platforms has significantly expanded their analytical capabilities by introducing features such as biocompatibility, tunable porosity, antifouling behavior, and mechanical flexibility. This review systematically categorizes hydrogel materials into four main types-nucleic acid-based, synthetic polymer, natural polymer, and carbon-based-and summarizes their functional roles in PEC sensors, including structural support, responsive amplification, antifouling interface construction, flexible electrolyte integration, and visual signal output.
