"Neon" is a generic term for sticking rarified noble gases (and maybe some metal vapor) in a tube and zapping it with high voltage alternating current.

The high voltage strips off the outermost electron, and when it pops back in, it releases a photon at the corresponding quantum level.

You get the same effect in an aurora. But noble gases are not corrosive.

Here is a transparent display that show the different noble gases.
