Researchers at the Regroupement Québecois sur les Matériaux de Pointe (RQMP) in Québec, Canada have assembled an organic light emitting diode (OLED) that uses thin and conductive single wall carbon nanotube sheets as the transparent electrode. The performance of their electrode rivals that of the transparent conducting oxide - indium tin oxide - currently used in commercial applications. The demonstration of this new technology recently appeared in the May online issue of Applied Physics Letters.
Organic light emitting diodes have in recent years emerged as a promising low cost technology for making large area flat panel displays and flexible light emitting fabrics. However, the fabrication of flexible OLEDs has up to now been held back by the fragility of the brittle indium tin oxide layer that serves as the transparent electrode. Constant bending of this layer unavoidably leads to cracking and device failure. By using carbon nanotubes, a highly conductive and flexible tube shaped carbon nanostructure, thin sheets a few tens of nanometers in thickness can be fabricated following a procedure akin to making paper. These sheets preserve the conductivity and flexibility of the carbon nanotubes and are thin enough to be highly transparent.
