Abstract
Organic light emitting devices including an electron transport-emission layer, and methods of preparing the same are included. The electron transport-emission layer may be an electron transport-red emission layer, an electron transport-green emission layer or an electron transport-blue emission layer. The methods produce high yields of the organic light emitting devices and are less expensive than conventional methods.
