White LED Lighting Grows Directly On Paper

White LEDs that can be printed and manufactured directly on paper have been developed by researcher Gul Amin from Linköping University.

With the development of this new technology, applications as diverse as luminous curtains, bright wallpaper that functions as lighting, self-lit books, etc., are possible.

Gul Amin, in his doctoral thesis at the Physical Electronics and Nanotechnology group, Campus Norrköping, demonstrated how it's possible for white LEDs to be grown directly on paper. And also, as an example, how to print them on wallpaper - the method for this is currently patent pending.

The LEDs, which are made from zinc oxide and a conducting polymer, can be manufactured directly on paper. The active components of the technology "are nanorods of zinc oxide on a thin layer of polydiethylflourene (PFO), a conducting polymer. But the paper has first been coated with a thin, water-repellent, protective and levelling layer of cyclotene, a resin."
