Construction of Ultra-stable Perovskite-Polymer Fiber Membranes by Electrospinning Technology and its Application on Light-Emitting Diodes

Abstract

Here, a photoluminescent functional PS fibre film was successfully constructed by doping a small amount of perovskite during the electrospinning process. Further, the water resistance, heat resistance and oxygen resistance of the MAPbBr3@PS fibre films were systematically studied. By changing the composition and type of metal halides and non-metal halides, the MAPbBr3@PS fibre membrane can cover the entire PL emission range. With commercial blue LED lamps as the light source, white LEDs have been successfully constructed using the MAPbBr3@PS film. It not only provides a method to improve the stability of perovskite but further expands the application of optically functional PS fibres in the field of optics.
