Caption

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