Nanotube Sheet Employed as OLED Electrode

Daniel S. Burgess

Organic LEDs (OLEDs) incorporating an anode made from a thin sheet of single-walled carbon nanotubes display performance similar to that of devices that employ indium tin oxide, report investigators in Montreal. The finding offers device designers an alternative to the transparent conductive ITO, which is brittle, heavy and relatively expensive. Richard Martel of Université de Montréal said that the most significant hurdle to the use of the nanotube sheets in OLEDs involves the availability of the material. He noted that companies such as Raymor Industries Inc. of Montreal are addressing...Read full article

    Referred to as SWCNTs, these cylindrical nanostructures composed of a folded sheet of graphene can be used as near-infrared markers for small animal multiplex imaging. Emitting at different wavelengths, which can be tuned in the visible or NIR region, SWNCTs provide photostable, narrow bandwidth fluorescence in a wide chromatic variety. That enables simultaneous imaging of a large number of spectrally separated markers, through the use of global hyperspectral imaging. In addition to being used...
