ORGANIC ELECTROLUMINESCENT ELEMENT ANF LIGHTING DEVICE |
摘要 |
An organic electroluminescent element that emits white light by energization may include a pair of electrodes; and two light-emitting layers provided between the electrodes, each of the light-emitting layers including a host material and a phosphorescence-emitting dopant. The host materials included in the respective light-emitting layers may be different from each other, at least one of the phosphorescence-emitting dopants included in the respective light-emitting layers may be a blue phosphorescence-emitting dopant having an ionization potential (Ip) of 5.3 eV or less, and at least one of the two light-emitting layers may include a plurality of the phosphorescence-emitting dopants. |
