Patent number: 8878164Abstract: The invention relates to an organic light-emitting diode, known under the abbreviation OLED, and to a method for the production of such an organic light-emitting diode. According to the invention, an OLED or organic light-emitting diode having an emitter layer (5) is produced, said emitter layer emitting white light in particular. The emitter layer (5) is arranged within a lossy, optical resonator. The optical path length between the two reflecting layers of the resonator determines the color of the light emitting from the optical resonator and, consequently, from the light-emitting diode. In order to be able to create a variety of colors, there must be different optical path lengths between the two reflecting surfaces. The correspondingly different distances can be produced in only one work step, in contrast to the prior art, by a photolithographic method.Type: GrantFiled: October 14, 2009Date of Patent: November 4, 2014Assignee: Universitaet zu KoelnInventors: Malte Gather, Klaus Meerholz

Patent number: 7901766Abstract: The invention relates to electronic devices whose electronic properties can surprisingly be improved to a significant degree by inserting at least one crosslinkable polymeric buffer layer, preferably a cationically crosslinkable polymeric buffer layer, between the conductive doped polymer and the organic semiconductor layer. Particularly good properties are obtained with a buffer layer in which crosslinking is thermally induced, i.e. by raising the temperature to 50 to 250° C. Alternatively, crosslinking can be radiation-induced by adding a photoacid. Moreover, such a buffer layer can be advantageously applied by means of printing techniques, especially inkjet printing, as the ideal temperature for the thermal treatment is independent of the glass transition temperature of the material. This avoids having to rely on material that has a low molecular weight, making it possible to apply the layer by means of printing techniques.Type: GrantFiled: September 4, 2004Date of Patent: March 8, 2011Assignee: Merck Patent GmbHInventors: David Christoph Müller, Nina Riegel, Frank Meyer, René Scheurich, Aurélie Falcou, Klaus Meerholz

Publication number: 20100308307Abstract: The present invention relates to an electronic device. Examples for such an electronic device are an optical detector, a laser diode, a field-quenching device, an optical amplifier, an organic solar cell or an organic light emitting diode. The electronic device comprises a cathode and an anode. One of the two electrodes is completely or partly transmissive to light. Between the two electrodes there are one or more organic semi-conducting layers and another organic buffer layer. The buffer layer can likewise be an organic, semi-conducting layer. For application of the buffer layer in porous form a solution is sprayed on. The solution preferably comprises a polar solvent and/or an electronic conductive additive. In addition the solution comprises a non-polar solvent and an organic material which is dissolved by the non-polar solvent. In one embodiment the solution to be sprayed on is atomized by an electrical field.Type: ApplicationFiled: September 26, 2008Publication date: December 9, 2010Inventors: Klaus Meerholz, Heike Klesper

Patent number: 5744267Abstract: A photorefractive (PR) device comprises of a layer of a novel photorefractive polymer composite sandwiched inbetween two transparent electrodes. The PR polymer composite comprises a photoconducting polymer, a photosensitizer, a novel second-order, non-linear optical chromophore, and a plasticizer in an amount sufficient to provide the PR polymer composite with a glass transition temperature below about 45.degree. C. The PR polymer composite is capable of internally storing image patterns generated by interfering two coherent light beams inside the material. The PR polymer composite shows high diffraction efficiencies (near 100%) and high net two-coupling gain (>200 cm.sup.-1). The writing of information is reversible. Consequently, the device is suitable for read/write holographic storage and real-time image processing applications, and is capable of being poled at essentially room temperature.Type: GrantFiled: September 10, 1996Date of Patent: April 28, 1998Assignee: Arizona Board of Regents acting for and on behalf of University of ArizonaInventors: Klaus Meerholz, Bernard Kippelen, Nasser N.
