摘要:
A method of forming an organic light-emitting device with improved stability including forming an anode over a substrate, providing a cathode spaced from the anode, and providing a donor element including light-emitting material and positioning such donor element in a material-transferring relationship with the substrate. The method further includes illuminating the donor element with radiation to cause the transfer of light-emitting material to deposit the light-emitting material to form an emissive layer over the anode, and forming an organic layer including an organic compound doped with a low work function metal or metal compound capable of acting as a donor dopant between the emissive layer and the cathode to lower the electron-injecting barrier from the organic layer into the emissive layer thereby improving the stability of the organic light-emitting device.
