| abstract |
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 irndium complex IrL 3 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 λ max =545 nm and λ max =595 nm respectively. |
