Fluorescence causes the light in neon signs. The following is a simple explanation of fluorescence using quantum theory.
Electricity excites the electrons around the neon nucleus, causing them to rise to a higher energy level. When the electron falls to its original energy level, the energy it absorbed is released as light. Because the energy levels in neon are the right distance apart, the energy released is of the right frequency to be seen by the human eye.
Neon can be used to light neon signs and to light glow lamps. :)
Its mostly Argon and a small amount of mercury. Its the main ingredients inside a flourescent lightbulb, which are used to light up billboards and highway signs. See the related link for more information on flourescent bulbs.
There is no naturally occurring neon blue color in nature. However, neon blue is a popular artificial color used in neon signs, lights, and certain products to create a bright, vibrant blue hue that stands out.
All signs which actually contain the element neon are about the same color. However, some signs which contain elements other than neon are sometimes referred to as 'neon' signs. In this case, the signs with different elements are different colors than true neon signs.
Some everyday uses for neon are in the billboards we see while we are driving down the road. It is also in the electric signs typically hung up in gas station windows that say,"OPEN". Neon, mixed with hydrogen, makes a gas that is put in refigerators.
Any of the noble gases. This can be Helium, Neon, Argon, Krypton, Xenon or even Radon. Neon, for example, makes red. Krypton makes a blue colour.

One career that involves working with neon is the business of making signs. Most signs that light up have neon gas in tubing that allows the light to glow brighter.

If you're referring to neon signs, the gas used is either neon, or argon (used with mercury). Fluorescent lights use the same principle as neon signs.
Tugsten No, its Neon. like Neon signs actually its not neon because neon is used for neon lights the questions states what is used in light bulb filaments not neon lights.
