    Abstract: There is disclosed an organic light-emitting device having at least one layer of light-emissive organic material arranged between first and second electrodes, one of the first and second electrodes being a multilayer structure, each layer of the multilayer structure being a DC magnetron sputtered layer. There is also disclosed an organic light-emitting device having two or more layers of light-emissive organic material arranged between first and second electrodes, an upper most layer of the organic material being more resistant to sputter deposition than an underlying layer of the organic material, and the electrode formed over the upper most layer of organic material being a sputtered layer. There is also disclosed methods for making such structures.

    Abstract: An organic photodetector (OPD) comprises a microcavity defined by a reflective electrode and a semi-transparent electrode, wherein the microcavity comprises a transparent conductive oxide layer and an active layer comprising an n-type organic semiconductor and a p-type organic semiconductor, and wherein the blend of the n-type organic semiconductor and the p-type organic semiconductor exhibits low absorption at the resonance wavelength, which results in an excellent optical sensitivity in a favorably narrow wavelength region and allows to tune the response to different wavelengths depending on the desired application. In addition, methods of producing such organic photodetectors and methods of tuning the resonance of a microcavity formed in an organic photodetector (OPD) to a predetermined wavelength are provided.

    Abstract: Apparatus for optically exciting fluorescence and detecting light is disclosed. The apparatus comprises a device for optically exciting fluorescence. The device comprises a transparent substrate having first and second opposite faces and a multilayer stack disposed on the second face of the substrate. The multilayer stack comprises a first layer having first and second opposite faces and a first refractive index and a second layer having first and second opposite faces and a second refractive index. The first face of the first layer is disposed on the second face of the substrate. The first face of the second layer is disposed on the second face of the first layer such that the first layer is interposed between the second layer and the substrate. The substrate has a third refractive index. The first refractive index is less than the second refractive index and the third refractive index. The device further comprises a light source carried by the first face of the substrate and arranged to emit light towards the first face of the first layer. The apparatus comprises a detector directed at the substrate, the substrate interposed between the waveguide and the detector for detecting fluorescence.
