When gallium is ionized on the cap of a field emitter, the optical emission emerges from right at the cap of the emitter. This optical emission was spectroscopically studied using an optical multichannel analyzer with a resolution of 1.3 Å over the range 1850-6500 Å.The dominant emission is due to Ga I radiation and is likely due to the two-body collision between atomic gallium and electrons.
