The gas used in fluorescent lamps is argon.
Neon is used for red lamps.
Sodium and Mercury are used in most street lamps. Some signs use the gas neon because it is bright and colorful.
Yellow-green "neon" signs are made using Argon with a drop of mercury which is vaporized when the sign is energized.
Neon for red lamps.

prevents soot generation
radium was used in luminous paint and for theglow in the dark clock it as it emits radioactive decay that's why its not used in luminous paint now
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
If the color is red, the element is neon, a noble gas.

At the end of the nineteenth century, luminous signs were a new phenomenon.
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.
Luminous signs are easier to find when there is an emergency.
As a gas inside luminous lights.
It gives off light. That is what luminous means.
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.

Neon gas is used in neon-signs, Vegas is full of them.
I't actually spelled Xenon and it's used in electric signs (some signs have Neon gas, others have Xenon)
Neon gas is a colorless odorless gas that fills tubes that are often used in electrical advertising signs.
