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...
