Hey hey
Just doing a little research on electrons to try and understand how a fluorescent light tube works.
From what I can fathom, an "ion" is an electrically charged group of atoms that can be either negatively charged or hold a positive charge. A "cation" A.K.A "positive ion" is a positively charged ion due to a deficiency in electrons which makes the ion attracted to the cathode inside a mercury filled glass tube (Possibly in a vacuum to reduce resistance?)
On the other hand an "Anion" A.K.A "Negative ion" is a negatively charged ion which is the result of an abundance of electrons within the ion and is therefore attracted to the anode inside the tube and this results in the electrons in the gas to emit photons at U.V frequencies which is just pure u.v light that can be seen reacting with the phosphorus found in washing powder that is left over as residue on clothes and the like (Only know that last bit from Stephen Hawkins "The theory of everything")
Anyhow so the tube is then coated on the inside with phosphor which makes the u.v light transform into a light that is in a spectrum that can be seen with the human eye usually 2700 to 6400k a.k.a (Warm white/cool white) spectrum for the majority of commercial U.V lighting.
Does this type of thing fall under the category of quantum physics? I hope this is ok to post in an electronics forum I just figured the two are kind of intertwining?
Is this correct?
