Abstract
An organic mixture includes a first emitter E1 and a second emitter E2. A formulation contains an organic mixture, and at least one organic solvent. An optoelectronic device contains an organic mixture and a formulation. The optoelectronic device, in particular the organic electroluminescent device, includes the organic mixture in its light-emitting layer, thereby exhibiting long device lifetime and narrow emission spectrum.
Claims16
An organic mixture, comprising a first emitter E1 and a second emitter E2, wherein,
- both the first emitter E1 and the second emitter E2 are fluorescent emitters;
- an absorption spectrum of the second emitter E2 at least partially overlaps with an emission spectrum of the first emitter E1;
- and
- a full width at half maximum (FWHM) of the emission spectrum of the second emitter E2 is less than 50 nm.
