Light up your room wallpaper!

Imagine a white luminescent curtains swaying breeze. Or at least … wallpaper covering your room perfect white light. Nothing fancy in such visions is gone. White LEDs based on zinc oxide and a conducting polymer can be made directly on the paper, as demonstrated in his thesis graduate student at the University of Linköping (Sweden) Gal Amin.

Young scientist has shown that it is possible is a "growing" white LEDs on paper, but also, for example, their "print" directly to the wallpaper. The patent application is filed.

The active component of such LEDs ZnO nanorods are located on the surface of a thin layer of conductive polymer polidietilflyuorena. However, the paper substrate must first be coated with water-repellent protective film. As Professor Magnus Villander, his first disciple built organic electronic and photonic inorganic semiconducting components directly on paper using chemical methods.

Learn more about "growing" LEDs on the paper can be found as most of the thesis and an article published in the journal Physica Status Solidi — Rapid Research Letters.

The main feature of the zinc oxide nanorods are — rather, a method for their preparation in a form allowing them to further use, e.g., in press (it is described in an earlier publication Journal of Material Science). This initial nanorods were grown by the hydrothermal method, and then crushed to obtain a porous ultrasonic powder which could be mixed with solvents used in the conventional hard coating process for zinc oxide nanorods, thereby forming the desired white LEDs. The method, of course, also patented.
