    摘要: An electroluminescent device comprises a semiconductor layer (4) in the form of a thin dense polymer film comprising at least one conjugated polymer, a first contact layer (5) in contact with a first surface of the semiconductor layer, and a second contact layer (3) in contact with a second surface of the semiconductor layer. The polymer firm (4) of the semiconductor layer has a sufficiently low concentration of extrinsic charge carriers that on applying an electric field between the first and second contact layers across the semiconductor layer so as to render the second contact layer positive relative to the first contact layer charge carriers are injected into the semiconductor layer and radiation is emitted from the semiconductor layer. The polymer film can be poly(p-phenyenevinylene) [PPV] of formula (I) wherein the phenylene ring may optionally carry one or more substituents each independently selected from alkyl (preferably methyl), alkoxy (preferably methoxy or ethoxy), halogen (preferably chlorine or bromine) or nitro.

    摘要: First and second electrodes (3 and 4) are provided on respective ones (2' and 2") of the first and second major surfaces of a photoresponsive zone (2). The photoresponsive zone (2) is in the form of a polymer blend having regions (2a) of a first semiconductive polymer and regions (2b) of a second semiconductive polymer phase-separated from the first semiconductive polymer. The second semiconductive polymer has an electron affinity greater than that of the first semiconductive polymer so that, in use of the device (1), a photocurrent between the first and second electrodes (3 and 4) resulting from light incident on the photoresponsive layer comprises electrons travelling predominantly through the second semiconductive polymer and holes travelling predominantly through the first semiconductive polymer.

    摘要: This invention relates to a device for electrooptic modulation of an optical beam. The device is a laminate comprising a coherent film of a conjugated polymer having semi-conducting properties as the active component laminated with two or more layers of electrically conducting, insulating or semi-conducting materials. At least the active component in the laminate is capable of interacting with the optical beam when under the influence of an electric signal and thereby result in a modulated beam. Means are provided for (i) establishing electrical contact with one or more layers of the laminate so as to enable an electrical signal to be applied across the active component and (ii) detection of the extent of modulation of the modulated beam emerging from the active component layer.
