1. A light emitting device comprising:
- a first electrode;
a hole transporting layer in contact with the first electrode;
a second electrode;
an electron transporting layer in contact with the second electrode; and
an emissive layer between the hole transporting layer and the electron transporting layer, the emissive layer comprising a metal-assisted delayed fluorescent (MADF) emitter, a fluorescent emitter, and a host, wherein the MADF emitter harvests electrogenerated excitons and transfers energy to the fluorescent emitter.
