    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.

    摘要： A process for forming a facial tris-cyclometallated iridium or rhodium complex isomer comprises heating an original solid composition containing meridional isomer of the metal complex at a temperature and for a time sufficient to form a product containing the facial isomer in an increased ratio to meridional isomer compared to the original composition.

    摘要： A method for forming a color organic light-emitting device including depositing a first electrode over a substrate; depositing a first emissive layer over the first electrode for producing a first colored light in response to hole-electron recombination; and selectively patternwise depositing a hole-blocking layer over the first emissive layer. The method also includes depositing a second emissive layer over the hole-blocking layer which in response to hole-electron recombination emits colored light different from the colored light emitted from the first emissive layer; depositing a second electrode over the second emissive layer; and whereby the patternwise deposition of the hole-blocking layer has been selected to substantially shift hole-electron recombination from the second to the first emissive layers.
