Nano Light-Emitting Fibers In the Lab 67
moscowde writes "Researchers at Cornell University have created a so-called Nano-Lamp — a microscopic collection of light-emitting fibers with dimensions of only a few hundred nanometers. The fibers are made of a polymer spiked with ruthenium molecules in a process dubbed 'electrospinning.' The bright spots on the fibers are smaller than the wavelength of the light they emit. The nanofiber glows bright orange when exposed to an electric field and can be seen in the dark with the naked eye. A professor at Princeton University called this 'a breakthrough in the way nanosize light sources are made.' Since the nanofibers are flexible, they could potentially be used in clothing or bendable computer displays."

Maybe offtopic, but that sounded SO SIMILAR to Farenheit 451... remember when Montag's wife asked him to put a new television in the last wall of their bedroom? *shudder*

2) put down a drop of it smaller than a wavelength
3) excite it with UV light or electrons
4) viola and arbitrarily small light source much smaller than a wavelength
Coat the tip of any nano fiber this way and it's still true.
Wha's the big deal? Atoms emit light from source smaller than a wavelength all the time.
What's tricky is that short of negative index materials you can't propagate light or confine light beyond the near field in areas less than the wa

Four questions about bendable screens (which I love the idea of. I would have to update my laptop if they come out with those.) I am not a scientist, so I have no clue what the answers could be.

1. This is not true. If you have a LG, Samsung, Motorola cell phone, then you are using the current technology, OLED (organic LEDs). Please look-up Samsung. On the "open market," Samsung has released their OLED screens (2005; http://www.physorg.com/news5318.html [physorg.com]). A possible outcome for the technology presented here is increasing the number of pixels/cm, smaller screen devices.

The fluorescent backlighting in your current laptop requires much more than this to light up right now, usually in the range of 400 - 10000 volts.
So scale down that voltage to this 'high' voltage of 100v, and compare to your current battery life and frequency of getting shocked when you drop it.

100 volts of electricity to make light that can only be seen in a dark room? Would we be able to power this via a battery for any length of time, and would I get electricuted[sic] if I dropped it?
Voltage != Power. Power is voltage times current (amps). Increased voltage is not directly connected to power usage, it all depends how much current goes with it. Current CCFL laptop display lights use voltages usually > 1000 volts without any problems with battery life or electrocution hazards.

Can you imagine the uses for bendable computer displays? Some would be amazing. You could have a roll-up monitor in your pocket like you see in science fiction movies.
Or there could be people wearing clothing made out of them covered in advertisements... That's what I'm afraid of. Imagine walking down the street and you see something bright coming towards you. You squint your eyes. As it gets close, you can make out the words emblazoned all over the body like a battle flag.
