Light emitting chemicals and electromagnetic fields.

AI Thread Summary
The discussion centers on the search for a liquid chemical that emits light when excited by an electromagnetic field. The original poster seeks a substance that can convert electrical energy into photons, potentially through aerosol spray. While chemiluminescence involves a chemical reaction, alternatives like phosphorescent materials, which glow after exposure to light, are mentioned. The concept of magnetoluminescence is introduced, highlighting its potential under varying magnetic fields. The conversation also touches on the nature of electromagnetic fields, clarifying that light itself is a manifestation of such fields. Suggestions include exploring thermoluminescent compounds for specific applications, particularly in relation to RF fields. Various resources, including Wikipedia articles and a handbook on thermoluminescence, are recommended for further exploration of these phenomena.

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

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 -

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
