someone just asked this as a comment on an article i was reading

http://home.howstuffworks.com/fluorescent-lamp6.htm

'Does a phosphor powder give off a photon or electron when struck by light?'

I was just thinking maybe a solar cell made of phosphor powder to emit electrons.

I failed chemistry at uni so yea =/, the answer might be obvious but i'd have no idea.

No, phosphors do not give off electrons when struck by light. However, phosphors do emit photons after being struck by other photons (within certain bands of light).
