Nanotube, Light Up!

... dots at the ends of the nanotubes, which causes excitation of electrons in them. The lifetime of an excited system is about 10 -10  s. Thereafter, the electron returns to the ground state. This transition is accompanied by the emission of a photon – electroluminescence takes place. Images of a shining cathode are similar to those of stars in the sky, with the color of these “stars” being mostly green with rare orange spots. The predominance of green dots indicates that the crystal structure ...
