We demonstrate green, yellow, and red top-emitting phosphorescent organic light emitting devices with Lambertian emission profiles and minimal color shift exceeding 20% external quantum efficiency. This is achieved through intentionally coupling exciton energy to the plasmon mode and then recovering the energy with a nanoparticle-based out-coupling structure.
