Carbon Nanotube Sheets as Electrodes in Organic Light-Emitting Diodes

by C. M. Aguirre et al. Applied Physics Letters, 1 May 2006 High performance organic light-emitting diodes (OLEDs) were implemented on transparent and conductive single-wall carbon nanotube sheets. At the maximum achieved brightness of 2800 cd m^–2 the luminance efficiency of our carbon nanotube-based OLED is 1.4 cd A^–1 which is comparable to the 1.9 cd A^–1 measured for an optimized indium tin oxide anode device made under the same experimental conditions. A thin parylene buffer layer between the carbon nanotube anode and the hole transport layer is required in order to readily achieve the measured performance. Read more
