    摘要: An electroluminescent device comprises a) a fluorescent light emitting layer comprising a fluorescent emitter and a fluorescent host material wherein the HOMO energy level of the fluorescent host material is not more than 0.1 eV more negative than that of the fluorescent emitter; b) a phosphorescent light emitting layer comprising a phosphorescent emitter and a phosphorescent host material; and c) a spacer layer interposed between the fluorescent light emitting layer and the phosphorescent light emitting layer; wherein the triplet energy of the fluorescent host material is not more than 0.2 eV less than the triplet energy of both the spacer layer material and of the phosphorescent host material. The materials within these layers are selected so that the HOMO and triplet energy levels satisfy certain interrelationships. The invention provides devices that emit light with high luminous efficiency.
