    • A method is described for preparing opto-electronic devices such as organic light-emitting diodes. The method is a thermal dye transfer process in which a dye pattern is transferred from a dye transfer plate into a receiving layer of a substrate by bringing the dye transfer plate into contact with the receiving layer and heating to a relatively low temperature, preferably below the vaporization or sublimation temperature of the dye. The pattern of the dye is maintained upon transfer and diffusion. Preferably, the method is repeated to provide a three-color pattern in the receiving layer. The invention also encompasses an opto-electronic device comprising a receiving layer as prepared by the aforementioned method wherein the receiving layer is sandwiched between two electrodes, one of which is transparent. Optionally, a hole-transporting or electron-transporting layer can be deposited between each electrode and the receiving layer.
    • 描述了一种用于制备诸如有机发光二极管之类的光电器件的方法。 该方法是通过使染料转移板与接收层接触并加热到相对低的温度,优选低于该温度的染料转移板将染料图案从染料转移板转移到基底的接收层中的热染料转移过程 染料的蒸发或升华温度。 在转移和扩散时维持染料的图案。 优选地,重复该方法以在接收层中提供三色图案。 本发明还包括一种光电器件,其包括通过上述方法制备的接收层,其中接收层夹在两个电极之间,其中之一是透明的。 任选地,可以在每个电极和接收层之间沉积空穴传输或电子传输层。
