Abstract The researches on polarized electroluminescence have attracted attention in recent years because of their potential applications in the field of liquid crystal display polarized backlights. The key to producing polarized light is the ordered orientation of anisotropic emission materials. Perovskite nanowires are an anisotropic one-dimensional nanomaterial with excellent optical properties. We used the off-center spin-coating method to fabricate the aligned CsPbBr3 nanowire films and obtained a photoluminescence polarization ratio of 0.46. The light-emitting diodes using the aligned nanowire film as the emission layer was fabricated and the device performance investigated.
