Is there a gas that will give off substantial amounts of UV radiation at varying temperatures?
Question Date: 2005-01-24
Answer 1:

There are gases that will give off UV if they are electrically excited. These include gases like mercury (when one makes it a gas) and xenon.

However, ALL gases will give off UV if they heated to high enough temperature, typically around 6000 degrees. This radiation (that comes out of hot objects) is called black body radiation.
