Cheap Recyclable nano lights

nano lights 150x150 Cheap Recyclable nano lightsUsing the new material graphene super, Sweden and American researchers have managed to produce a new type of lighting components. It is cheap to produce and can be completely recycled.The invention, which paves the way for the shiny wallpaper made entirely of plastic, for example, is published in the journal ACS Nano by scientists at Linköping University and the University of Umea, Sweden, and Rutgers, State University of New Jersey.Ultra-thin electricity-saving organic light emitting diodes, which is called OLED, recently introduced commercially in mobile phones, cameras, televisions and super-thin. An OLED is a light-generating layer of plastic sandwiched between two electrodes, one of which must be transparent. OLED today have two drawbacks – which are relatively expensive to produce, and the transparent electrode is the metal oxide and indium tin alloy. The latter presents a problem because the Indian is both rare and expensive and, moreover, is difficult to recycle. Now researchers from the universities of Linköping and Umeå, in collaboration with U.S. colleagues, presents an alternative to OLED, organic light-emitting electrochemical cell (LEC). It is cheap to produce, and the transparent electrode is made of carbon material graphene.“This is an important step in the development of organic lighting components, both technologically and environmentally. Organic electronic components promise to be very common in new and interesting applications in the future, but this can create significant problems for recycling. Using graphene instead of conventional metal electrodes, the components of the future will be far easier to recycle and thus attractive environment, “says one scientist, Nathaniel Robinson of the University of Linköping.From all parts of the LEC can be produced from liquid solutions, it is also possible to LECs in a roll to roll in the process, for example, a printer in a highly cost effective manner.“This paves the way for cheap plastic production based entirely on lighting and display components as large flexible sheets. This type of lighting or the screen can be rolled or applied as wallpaper or on rooftops “says another of the scientists, Ludvig Edman, University of Umeå.Graphene consists of a single layer of carbon atoms and has many attractive features as an electronic material. It has a high conductivity, is almost transparent, and can also be produced as a solution in the form of graphene oxide.Researchers around the world have been trying to replace the indium tin oxide for more than 15 years. Indium is a rare commodity, and the alloy has a complicated life cycle. The raw material for all organic and metal-free LEC, on the other hand, is inexhaustible and can be completely recycled – as fuel, for example.

I am just wondering how long until they can turn these nano lights into something more sophisticated like a paint I could put on my ceiling that each nano light could communicate with each other to be able to turn my ceiling into a night under the stars or be able to watch the Super Bowl or answer emails on my back That would be cool.  Could also think of alot of commercial applications this could be used for if the nano lights become programable in the future.
