Abstract
The present invention provides an OLED with an emissive region comprising a plurality of sets of organic layers, each set comprising a non-continuous emissive layer and a neat non-emissive layer. The present invention also provides an OLED with an emissive region comprising a plurality of sets of organic layers, each set comprising an emissive layer and a neat non-emissive layer, wherein the energy gaps of the emissive layer and the non-emissive layer are not nested. The present invention also provides a method for making OLEDs by depositing on a substrate an anode, a plurality of sets of organic layers, each set comprising an emissive layer and a non-emissive layer wherein each layer is deposited sequentially, and a cathode.
