1. A method comprising:
- a. providing a first electrode;
b. depositing a first organic layer over the first electrode via solution processing, the first organic layer further comprising;
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;
iv. a third organic emitting material of the first organic layer;
wherein the first, the second, and the third organic emitting materials are co-doped in the organic host material;
c. depositing a second electrode over the first organic layer;
wherein the amount of the first organic emitting material of the first organic layer is measured to a variance of less than 5%.

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.
