Embodiment 1

[0043] Example 1: Fabrication of organic electronic devices with double-layer and triple-layer cathodes

[0044] Two organic light-emitting devices were fabricated according to the following procedures. The device was placed on a glass substrate that had been previously coated with indium tin oxide (or ITO) (Applied Films). An approximately 65 nm thick layer of poly(3,4-ethylenedioxythiophene / polystyrenesulfonate) (PEDOT) (Bayer) was deposited by spin coating on the UV-ozone treated ITO substrate. The layers were fired in air at 180° C. for 30 minutes. The PEDOT-coated ITO substrates were transferred into a controlled-atmosphere glove box with less than 1 ppm of moisture and oxygen. A layer of blue light-emitting polymer (ADS329BE from American Dye Source, Quebec, Canada) with a thickness of approximately 70 nm was spin-coated on the PEDOT layer. at 2 x 10 -6 The cathode material is thermally evaporated under a vacuum of torr. In one case, the cathode consisted of 4nm NaF...

Abstract

The invention provides an organic electronic device comprising: (i) a multilayer cathode (10) comprising: (a) a conductive layer (12) that is electrically connected as a bus, (b) a layer (14) comprising at least one source of alkali metal ions, alkaline earth metal ions, or lanthanide ions and (c) a conductive metal layer (16) comprising at least one conductive metal species; (ii) at least one electro-active organic layer (22); and (iii) an anode (24) that is electrically connected to the conductive metal layer.

Description

technical field [0001] The present invention relates to organic electronic devices. In particular, the present invention relates to metal compound-metal multilayer electrodes for organic electronic devices. Background technique [0002] The efficient operation of organic electronic devices depends, among other factors, on the efficient transport of charges between electrodes and adjacent media. Organic electronic devices are used in several applications based on converting electricity into light and / or converting light into electricity. Exemplary electroactive devices of the type organic or inorganic devices are well known in the art of graphic display and imaging. Electroactive devices of various shapes and sizes have been produced for use in a variety of applications. However, inorganic electroactive devices generally require high excitation voltages and have low brightness. On the other hand, organic electroactive devices developed in recent years have lower excitatio...
