Abstract

The present invention relates to organic electroluminescent devices comprising a light-emitting layer B comprising a host material, a phosphorescence material and a emitter material, which exhibits a narrow—expressed by a small full width at half maximum (FWHM)—green emission at an emission maximum of 500 to 560 nm. Further, the present invention relates to a method for generating green light by means of an organic electroluminescent device according to the present invention.
