摘要： The invention relates to a transparent and flexible organic multilayer diode device based on electrospun polymer fibers and iridium organometallic compounds and fabrication method. The diode device includes electrospun polymer fibers that have been coated with metal as the anode, conductive polymer as the hole carrier, iridium-based organometallic compounds as the emissive layer, lithium fluoride as a buffer, and metal as the cathode. The process for obtaining the device involves electrospinning the polymer fibres and successively depositing the layers in the following order: anode, hole transport layer, emissive layer, buffer layer and cathode layer and attaching said structure to a flexible and transparent substrate.
