Abstract Ultraviolet band C photodetectors (UVC PDs), which can convert the UVC light (200–280 nm) signals into detectable signals, have received tremendous attention due to their wide applications in bio‐medicine, communications, and imaging fields. However, current research primarily focuses on either conversion of electrical or its visible signals. Here, a flexible dual‐detectable PD based Ca 2 Nb 3 O 10 nanosheets CsCu I film is reported, simultaneously achieving visual detection for invisible light. The exhibits exceptional self‐powered (270 nm; 1.87 mW cm −2 ) abilities with high responsivity (R) 16.7 mA W −1 , an impressive detectivity 6.1 × 11 Jones, on/off ratio 3789, ultra‐high UVC/UVA (R 270 /R 360 rejection 2.1 5 . shows great application potential safety communication real‐time imaging. This work proposes new type through material selection structural design, thereby inspiring novel ideas enhance convenience practicality photodetection.

Abstract The rapidly developing Artificial Intelligence era has an increasing demand for high‐performance organ‐on‐a‐chip systems, especially the vision system, which is most essential perceptual system human beings. However, traditional artificial systems require multiple functional components, are not favorable integration. Neuromorphic visual sensors (NVSs) inspired by retina combine sensing and preprocessing functions. NVSs complex structures to achieve both photo memory, difficult be large‐scale fabricated. Here, a novel In 2 O 3 ‐Ga (InGaO) thin‐film‐based NVS with high photosensitivity superior photomemory performance proposed, can avoid multilayer structure. device possesses accuracy optical communication retina‐like Notably, this InGaO achieves of UV light, it been experimentally confirmed have excellent photoelectric synaptic under 254 nm 365 illumination. This work provides feasible strategy assist eye in invisible light.
