Metal-free light-emission demonstrated

In a publication in ACS Nano, we have shown how light-emitting compenents called polymer LECs can be made without any metal electrode.  In this case we used graphene as a cathode, which allowed us to use the printable polymer PEDOT:PSS as the anode.  The mobile ions in the LEC allow a variety of materials to be used as these electrodes, in sharp contrast to OLED technology.

More information is available in the original article, or via media reports.  A few are listed below.
