    摘要： The invention relates to a matrix of electroluminescent organic material having quantum dots embedded therein. Electrodes provide electrons and holes to the matrix forming excitons to be transferred to the quantum dots. The invention provides transfer molecules on the quantum dots facilitating the transfer of excitons from the electroluminescent organic material to the quantum dots, by first transferring them to the transfer molecules. The transfer molecules are chosen to make a transfer rate of excitons from the organic material to the transfer molecules larger than a decay rate of excitons in the organic material. More specifically, the organic matrix forms a light emitting layer in a light emitting device (LED). Also, the electroluminescent organic material is preferably an electroluminescent polymer.

    摘要： An electroluminescent device includes a first electrode, a second electrode and, dispersed therebetween, an electroluminescent layer comprising a first and a second electroluminescent compound capable of emitting light of a first and a second color respectively, the first color being different form the second color. The electroluminescent device is capable of reversibly emitting light having predominantly the first color when biased at a low voltage in a first direction and light having predominantly the second color when biased at a low voltage in a second direction opposite to the first direction. The first electroluminescent compound may be an electroluminescent polymer or low-molecular weight conjugated electroluminescent compound. The second electroluminescent compound is a metal-ion complex, typically mono-kernel or bi-kernel, having one or more ligands. At least one of said one or more ligands is substituted with a conjugated moiety, such as an oligo-phenylenevinylene or an oligo-phenylene derivative. The metal-ion complex is an ionic compound and has counter ions for balancing the charges of the metal ion which are capable of migrating within the electroluminescent device when the electroluminescent device is biased.

    摘要： The invention provides a method and a device for label-free detection of biomolecules or analytes in a sample liquid. The method comprises the steps of allowing an analyte to bind to one of at least two conductive surfaces. An alternating electrical field between at least two conductive surfaces. Amplitude and phase of alternating current, flowing between the at least two conductive surfaces, are compared with amplitude and phase of reference signal. From the difference between both currents it is possible to determine whether an analyte is present at the conductive surface.
