Swedish and US researchers have developed a new lighting technology that could lead to innovations like illuminated wallpaper made entirely of plastic and cheaper, more easily recycled electronic devices. This new super material is called: graphene.

Organic light-emitting electrochemical cell (LEC). It is inexpensive to produce, and the transparent electrode is made of the carbon material graphene.

Graphene consists of a single layer of carbon atoms and has many attractive properties as an electronic material. It has high conductivity, is virtually transparent, and can moreover be produced as a solution in the form of graphene oxide.

Graphene is used instead of conventional metal electrodes--and since everything in an LEC, including the graphene, can be created from liquid solutions, they will be able to be produced through a printing process. The researchers says that this makes them much more efficient and less expensive than OLED lighting
