Perovskite light-emitting/detecting bifunctional fibres for wearable LiFi communication

摘要

a Schematic illustration of the multiple dip-coating process of transparent electrodes and QDs in the fabrication of a perovskite fibre. b Schematic of the hybrid strategy of QD inks. c Photographs of as-prepared QD fibres, and corresponding AFM images. d Schematic illustration of the dynamic dip-coating process. e Perovskite fibres arranged into a ‘NUST’ pattern under UV illumination (RGB emission fibres were made with hybrid CsPbI3, CsPbBr3, and CsPb(Br/Cl)3 inks). Insert, perovskite fibres being prepared on Zn and Ag wires, and their corresponding PL images under UV illumination. f Photographs of the perovskite fibres woven together into a lattice under UV illumination. g Photograph of perovskite fibres assembled into one multicolour emission fibre under UV illumination.
