Abstract:
1. An organic light-emitting diode luminaire comprising a first electrode, a second electrode, and an electroluminescent layer therebetween, the electroluminescent layer comprising: a first electroluminescent material having an emission color that is blue-green, wherein the first electroluminescent dopant is an organometallic complex of Ir; and a second electroluminescent material having an emission color that is red/red-orange, wherein the second electroluminescent dopant is an organometallic complex of Ir; wherein the weight ratio of (first electroluminescent material):(second electroluminescent material) is in the range of 10:1 to 100:1; wherein the additive mixing of the two emitted colors results in an overall emission of white light; and a host material having a triplet energy high enough so that it does not quench the emission from the organometallic electroluminescent dopants.
