Beschreibung
Zusammenfassung:	The invention relates to a light-emitting device comprising at least a substrate, an anode, a light-emitting layer and a cathode whereby the light-emitting layer contains an iridium complex IrL3 and whereby at least two ligands L are a dibenzoquinoline. The invention relates in particular to the complexes Ir(dibenzo[f,h]quinoline)2(pentane-2,4-dionate) and Ir(dibenzo[f,h]quinoline)3 which emit light with a wavelength of λmax=545 nm and λmax=595 nm respectively.
