Abstract
Luminescent materials based on fluoroplastic and perovskite nanoparticles with the composition of CsPbBr3, synthesized from precursors previously added to the molding solution, were obtained using the electrospinning technique. It has been demonstrated that CsPbBr3 nanoparticles can be successfully encapsulated in hydrophobic fibers with a diameter of 0.6 ± 0.1 μm. Bright luminescence at a wavelength of 508-510 nanometers (excitation at 380 nm) has been found to persist for at least nine months, indicating the stability of the material against external factors.
