Light-emitting devices comprising light-emitting diodes are described herein. These devices may include a substrate, a reflective anode, a hole-injection layer, a hole-transport layer,an emissive component, an electron-transport layer, a cathode, an enhancement layer, and a light-scattering layer. The emissive component may include first and second fluorescent light emitting layers with an intervening phosphorescent light-emitting layer or first and second phosphorescent light-emitting layers with an intervening fluorescent light-emitting layer. |
