I am stumped, and googled out.

I am interested in knowing whether or not anyone knows of a chemical in liquid form, that will glow or emit light when it is excited by electrons, or more specifically an electromagnetic field.

If I am generating an electromagnetic field and want to be able to use an areosol spray to illuminate that field I would pretty much have to have a liquid chemical that can transform electrical energy into photons right?

Just curious!

Thanks in advance for any answers pro or con.

Well, there is chemiluminescence, but that means a chemical reaction.

In non-destructive testing, one method is dye penetrant testing in which one uses a dye that is illuminated by a UV light, which is phosphorescent.

Some materials are phosphorescent after exposure to visible light - "some glow in the dark" chemicals.

See - http://en.wikipedia.org/wiki/Phosphorescence
http://en.wikipedia.org/wiki/Photoluminescence

http://www.rp-photonics.com/photoluminescence.html

Certainly a static magnetic field will not induce phosphorescence, but a time varying one might if the energy is sufficient.

One might search for "Magnetoluminescence" on Google - there appears to be a fair amount of sites mentioning this. But one might add other qualifiers like "theory".

What do you mean by electromagnetic field ? That's what light is ! A photon is a quantum of an electromagnetic field.

Please clarify - what kind of field generator are you using ?

Gokul prompted a thought - if it's an RF field, e.g. microwave, then perhpas some thermoluminescent compound would be appropriate. Otherwise, you're pretty much stuck with visible or UV.

Some background - http://en.wikipedia.org/wiki/Thermoluminescence

Maybe look into this book -

1. What are light emitting chemicals and electromagnetic fields?

Light emitting chemicals are substances that are capable of producing light through a chemical reaction. Electromagnetic fields are areas of space where electric and magnetic forces interact, resulting in the propagation of electromagnetic waves.

2. How are light emitting chemicals and electromagnetic fields used?

Light emitting chemicals are commonly used in products such as light bulbs, fluorescent lamps, and electronic displays. Electromagnetic fields are used in various technologies, including radio communication, medical imaging, and power generation.

3. Are light emitting chemicals and electromagnetic fields harmful to humans?

The safety of light emitting chemicals and electromagnetic fields depends on their intensity and duration of exposure. In general, low levels of exposure are not harmful to humans, but prolonged or high levels of exposure can have negative health effects.

4. Can light emitting chemicals and electromagnetic fields be found in nature?

Yes, light emitting chemicals can be found in some bioluminescent organisms, such as fireflies and deep-sea creatures. Electromagnetic fields also occur naturally, such as in the Earth's magnetic field and in lightning strikes.

5. How can we protect ourselves from potential harm from light emitting chemicals and electromagnetic fields?

To minimize potential harm, it is important to limit exposure to these substances and fields. This can include using protective equipment, following safety guidelines, and reducing overall exposure time. It is also important to stay informed about potential risks and to follow recommended safety precautions.
