Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals called phosphors are used to produce other colors, such as hydrogen (purple-red), helium (yellow or pink), carbon dioxide (white), and mercury (blue). Neon tubes can be fabricated in curving artistic shapes, to form letters or ...
A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."
Helium–neon laser at the University of Chemnitz, Germany. A helium–neon laser or He–Ne laser is a type of gas laser whose high energetic gain medium consists of a mixture of helium and neon (ratio between 5:1 and 20:1) at a total pressure of approximately 1 Torr (133 Pa) inside a small electrical discharge.
The neon gas used in some nixie tubes includes a small amount of mercury vapor (for various reasons), which glows blue. A Penning mixture of neon and argon is also used as a starter gas in sodium vapor lamps , where it is responsible for the faint pinkish glow before the sodium emission begins.
