360° detection of linear ZnO@CFs photoelectrochemical-type ultraviolet photodetector

Applications of omnidirectional ultraviolet (UV) detectors are numerous and promising. There is an increasing demand for flexible UV toward the realization intelligent weavable systems. Carbon fibers (CFs) used in due to their linear structure unique flexibility. In this work, a photoanode photoelectrochemical (PEC)-type photodetectors (PDs) based on wurtzite hexagonal-phase ZnO nanowires grown CFs developed. The PD ZnO@CFs has good response rotation angles range from 0° 360°. After being bent twisted several hundred times, still exhibits stable switching period. Furthermore, detector shows photocurrents up 185 μA cm−2, reproducible periods, fast rising falling times 0.17 0.12 s, respectively, excellent spectral selectivity 300–400 nm. proposed potential applications wearable PEC with 360° detection.
