Abstract: A method of fabricating an organic light emitting device is provided. A first electrode is provided, over which the rest of the device will be fabricated. A first organic layer is deposited over the first electrode via solution processing. The first organic layer includes: i. an organic host material of the first organic layer; ii. a first organic emitting material of the first organic layer; iii. a second organic emitting material of the first organic layer; A second organic layer is deposited over and in direct contact with the first organic layer. The second organic layer includes an organic emitting material of the second organic layer. A second electrode is then deposited over the second organic layer. The device may include other layers.
