My son has been doing similar research for several years doping gallium to grow nanowires, then creating tools to manipulate them. The result is paired nanowires, one tipped with a LED and the other with a receptor, in a variety of wave lengths. A huge step forward in sizing optic fibers.

Problem is, the switch is too small to find. I haven’t slept properly for weeks and my electric bill is insane.

One of these days they’ll come up with a commercial use for graphene. So far it’s only been a windfall for researchers.

If graphene responds to heat even better than tungsten, doesn't that imply that you could use it to make longer-lasting, more efficient, incandescent light bulbs?

Anyone know what the color spectrum is like?

I've been wondering... what happens if you heat a nanoparticle - that is a solid particle made up of atoms that is much smaller than a wavelength of visible light - to a temperature high enough to cause a black body to radiate in the visible or infrared wavelength range.

In other words, what happens if a particle of matter is heated up enough to radiate light, but the particle much smaller than the wavelength of the light it is trying to emit. Does it still emit? If so, how? Does it "bottle up" heat inside itself until its temperature gets high enough to emit at a wavelength compatible with its size? For some nanoparticles, such a temperature would vaporize them or even ionize them.

Can a point source be a tiny fraction of one wavelength in its longest dimension?

A candle wick glows bright enough to be seen by the naked eye.

This is amazing! And VERY cool about your Son!

The bulb is one atom thin, however the 14/2 Romex electrical wire to connect it.......
