In Need of a Gas that Fluoresces Under UV light
« on: March 02, 2012, 02:33:53 PM »
Hello Everyone,

I am trying to find a substance that is in its gas phase between 21 and 37 degrees Celsius (70-100 degrees f) and between 10 and 200psi of pressure, that emits light in the visible spectrum when excited by a ultraviolet light source.

Ideally the gas would also be colorless in the visible spectrum but isn't required.

Basically, I am looking for a gas that would glow under a black light similarly to how some minerals do. Having a gas with these properties would be very useful in a few engineering applications I am currently exploring and I was wondering if anyone knows of any substances that has the properties outlined above or if anyone knows if such a substance can even exist. Its been awhile since I did any photochemistry.

I suspect this is going to be difficult, if not impossible, to achieve.  By definition, molecules of gas a diffuse, a small amount of matter widely separated.  You won't have enough material in one place to generate much light.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

If no gas is efficient enough at absorbing UV, maybe you could accept a fine powder or mist in the gas?

Both of those would work provided I could prevent the powder/mist from collecting on the sides of the chamber containing it
