  • Publication number: 20200386702
    Abstract: A gas sensor includes first and second electrodes (107, 109) and a first semiconductor layer (113) comprising a semiconducting transition halide or pseudohalide, for example copper thiocyanate, in electrical contact with the first and second electrodes. The semiconducting transition metal halide or pseudohalide provide that a semiconductor based gas sensor is sensitive to alkenes and can detect low concentrations of alkenes. Furthermore, the gas sensor may comprise a second semiconductor layer (111), different from the first semiconductor layer. The second semiconductor layer is preferably an organic semiconductor. The gas sensor may be a top-gate or bottom-gate thin film transistor (103: gate electrode; 105: gate dielectric) or a horizontal or vertical chemiresistor. The gas sensor may be used for detection of alkenes, for example ethylene or 1-MCP.

  • Publication number: 20200381644
    Abstract: An organic photodetector comprising an anode (103), a cathode (107) and a layer (105) comprising an organic electron donor and an organic electron acceptor between the anode and the cathode wherein the weight of the organic electron acceptor is less than 2 times that of the electron donor. The organic electron acceptor may be a fullerene. The organic electron donor may be a conjugated polymer.

  • Publication number: 20200271621
    Abstract: A gas sensor system is made up of a first gas sensor that is sensitive to both a target gas (200) and a secondary gas and a second sensor (300) that is only sensitive to the target gas. The response of the two gas sensors is processed to detect a presence of or a concentration of the target gas. The first sensor includes a semiconductor material that is sensitive to the presence of both the target and the secondary gas and electrodes that are sensitive to the presence of the target gas. The second sensor includes a semiconductor material that is sensitive to the presence of both the target and the secondary gas, but also includes a blocking layer on a surface of at least one of the electrodes that prevents the second gas interacting with the electrodes.

  • Publication number: 20200227642
    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.

  • Publication number: 20200209158
    Abstract: An analytical test device (12) includes one or more light emitters (13) configured to emit light within a first range of wavelengths (??a). The analytical test device (12) also includes one or more first photodetectors (14), each first photodetector (14) being sensitive to a second range of wavelengths (??b) around a first wavelength. The analytical test device (12) also includes one or more second photodetectors (15), each second photodetector (15) being sensitive to a third range of wavelengths (??c) around a second wavelength, the second wavelength being different to the first wavelength. The analytical test device (12) also includes a correction module (16) configured to receive signals (19, 20) from the first and second photodetectors (14, 15) and to generate a corrected signal (21) based on a weighted difference of the signals (19, 20) from the first and second photodetectors (14, 15).
