چکیده
Metal halide perovskite quantum dots (PQDs) are widely used in the display field due to their excellent photoelectric properties, such as ultra-narrow half-peak widths and ultra-pure luminescence color purity. Inkjet printing, laser direct writing electrospinning all common methods for PQDs printing prepare micropattern displays. In order produce large-scale high-resolution micropatterns, electrohydrodynamic (EHD) technology is capable of deposition highly oriented nanofibers on rigid or pliable, flat bent substrates with advantages real-time regulation single control. Therefore, it has a lot potential fabrication pliable electronic devices one-dimensional ordered light-emitting fibers. Polycaprolactone (PCL) an EHD polymer material superior biocompatibility, low melting point, saving energy easy degradation. By synthesizing CsPbBr3 (QDs) PCL composite spinning stock solution, we self-built platform PCL@CsPbBr3 optical fiber realized flexible micropatterns polydimethylsiloxane (PDMS) packaging. An x-ray diffractometer (XRD), scanning electron microscope (SEM) photoluminescence (PL) were characterize analyze fiber’s morphology, phase spectral characteristics. may open up interesting possibilities applications based metal PQDs.
