Abstract:
A method for forming an organic light-emitting device with improved performance comprising the steps of:a) forming an anode over a substrate; b) providing a donor element including light-emitting materials and positioning such donor element in a material-transferring relationship with the substrate; c) illuminating the donor element with radiation to cause the transfer of light-emitting material to deposit the light-emitting material and form a light-emitting layer over the anode; d) forming a performance-enhancing layer over the light-emitting layer including one or more chemical reducing materials selected to improve the performance of the organic light-emitting device by reducing the effect of oxygen or moisture contamination of the light emitting layer; e) forming an electron-transporting layer over the performance-enhancing layer; and f) forming a cathode over the electron-transporting layer.
