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.
