摘要:
Die Erfindung betrifft ein Verfahren zum Herstellen insbesondere dotierter Schichten für elektronische, lumineszierende oder photovoltaische Bauelemente, insbesondere OLEDs, wobei ein oder mehrere flüssige oder feste Ausgangsstoffe in einer Quelle (11, 12, 13, 14) verdampfen oder als Aerosol einem Trägergas beigemischt werden und in dieser Form in eine Depositionskammer (1) transportiert werden, wo sie insbesondere in Folge eines Temperaturgradienten eine dotierte Matrix bildend auf einem Substrat (5) kondensieren. Zur Verbesserung der Dotierung von elektronischen, lumineszierenden oder photovoltaischen Schichten, wird vorgeschlagen, dass die Dotierung durch Modifikation eines Ausgangsstoffes während seines Transports erfolgt.

The invention relates to an optoelectronic device being usable in a vehicle, a computer, a television, a printer, a large area wall, theater or stadium screen, a billboard or a sign, wherein the optoelectronic device includes an OLED, in which emission from the device is obtainable via a phosphorescent decay process, and wherein the OLED comprises a material that is capable of receiving the energy from an exciton triplet state and emitting that energy as phosphorescent radiation.
摘要:
A novel class of low reflectivity, high transparency, non-metallic cathodes (1) useful for a wide range of electrically active, transparent organic devices is disclosed. As a representative embodiment, the highly transparent non-metallic cathode (1) of an OLED employes a thin film of copper phthalocyanine (CuPc) (6) capped with a film of low-power, radio-frequency sputtered indium-tin-oxide (ITO). The CuPc prevents damage to the underlying organic layers during the ITO sputtering process. Due to the low reflectivity of the non-metallic cathode, a non-antireflection-coated, non-metallic-cathode-containing TOLED is disclosed that is 85 % transmissive in the visible, emitting nearly identical amounts of light in the forward and back-scattered directions.

The present invention provides complexes of the formula(L)M(X),in which M is a metal atom selected from copper,silver and gold;L is a carbene ligand; and X is a monoanionic ligand. The complexes are useful as light emitters in the emissive zone of light-emitting devices such as OLEDs. The present invention also provides organometallic complexes which exhibit RASI photoemission, and the use of the same in light-emitting devices such as OLEDs.

The present invention relates to organic light-emitting devices comprising (a) an anode, (i) a cathode, and (e) an emitting layer between the anode and cathode, comprising 40.01 to 99.95% by weight of a luminescent organometallic complex X having a difference of the singlet energy (ES1(X)) and the triplet energy (ET1(X)) of smaller than 0.2 eV [Δ(ES1(X))−(ET1(X)) ES1(Y)]. By doping, for example, an emitting layer containing a luminescent organometallic complex having a small S1−T1 splitting, with a fluorescent emitter the emission decay time can significantly be shortened without sacrificing external quantum efficiency (EQE) because of very efficient energy transfer.
