Subject: What chemicals are in highlighters?

Previously, someone asked about what highlighters are made out of, however, the
answer seem to be explaining the mechanism of action of the glow. 

I was wondering what chemicals are in highlighters?

I'm asking this question because I was able to revive the highlighter by
sticking it in alcohol, but that seemed to have diluted the ink... (yes,
studying for finals.) so I guess more specifically, I'm asking two things:

What's the chemical that makes the glowing ink?
What's the excipient that allows the flow of the ink?

Thank you!!!
