Nano World: Bright nanotubes for telecom

Charles Q. Choi: Carbon tubes only nanometers or billionths of a meter in diameter could serve as ultra-bright light sources for telecommunications, IBM scientists told UPI's Nano World. Conventional solid-state light sources such as light-emitting diodes, or LEDs, bring together positive and negative charges. When those charges neutralize each other, they emit pulses of light, or photons.
