natural - lightening, the auroraman made - neon and florescent lights
by making light
In a cobweb, near florescent/bright lights, and on your food!
A florescent tube is still a mercury vapour device and needs the mercury to vaporise to have the tube conduct to emit visible light.
Yes. The cells in a plasma TV contain a mixture of gases that are typically found in neon lights. When a current is passed through the cell, it ionizes the gas, turning it into a partially ionized plasma. This plasma differs from the plasma found in the Sun, stars, and interplanetary, which is typically fully ionized, and hotter.
For PLASMA tv and lights
Many things contain plasma mostly things in the sky.
A Plasma must contain many ions and electrons.

The sun, arc welding, "black lights" (looking fro fluorescence). [inside florescent lights - but its blocked by the surface of the bulbs.)
