Neon

The more important application of this substance is in the filling of tubes for luminous advertises (neon tubes). These tubes consist in a neon and helium or argon low-pressure mixture submitted to electrical discharges. The color of the emitted light depends on the composition of the gaseous mixture and of the color of the glass of the tube; with pure neon and colorless tubes we can obtain a red light and with the mixtures above referred we can see a blue shine. The neon is also used in fluorescent lamps, warming lamps for electronic equipment, stroboscopic lamps for motion control of machines, as a filling gas of Geiger-Muller counters, in scintilators and ionization cameras and other devices for radiation detection. It is also used in the production of lasers of this gas, in a pure state or mixed with helium.
