White LEDs Lighting Directly On Paper

ScienceDaily (July 10, 2012) — Imagine a white luminous curtain waving in the breeze. Or wallpaper that lights up your room with perfect white light. The applications are not very far away.White LEDs, made from zinc oxide and a conducting polymer, can be manufactured directly on paper, as shown by Gul Amin in his doctoral thesis at Linköping University.

Imagine a white luminous curtain waving in the breeze. Or wallpaper that lights up your room with perfect white light. These might sound like flights of fancy, but the applications are not very far away.
In his thesis, Gul Amin, who recently received his doctorate at the Physical Electronics and Nanotechnology group, Campus Norrköping, shows how it is possible to grow white LEDs directly on paper and also to print them on wallpaper for example -- this method has a patent pending.
The active components 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.

This would be pretty cool. Having a room with dimmable, glowing walls to light things.

1. like that scene in "2001: A Space Odyssey" where Dave is in the all white lit room nt

2. Or how about just not using the lights?

Other than the bathroom, I think the lights in my apartment have only been on for about three total hours so far this year. It's hard in the winter since you have to prepare dinner earlier in the day, but it is the right thing to do. Instead of doing what is right, I see the vast majority of my neighbors participate in conspicuous consumption by showing off their wealth by leaving lights on for hours. I hate my neighbors for that. I live in one of the most liberal areas of the country, and they still do right-winger crap like that.

3. That's an ongoing point of contention in our house

My wife gets annoyed with me when I turn lights off wherever nobody is actively doing anything. She just likes everything to be bright. *sigh* And she doesn't even have the excuse of not believing in the negative environmental impacts of our profligate energy use...

5. I keep a couple of

solar/wind up LED lanterns around for night use. It makes energy efficiency fun, like I'm in colonial times, except without the hazardous oil lantern. But I applaud your restraint.

6. You might like some 0.5 watt LED bulbs, like I use

They are the equivalent of about a 15 watt conventional bulb and 2 or 3 of them will light up a house adequately for most purposes.

It is the computer that uses the electricity at my place.

4. Imagine you can afford to spend

thousands of dollars on lighting.
