What frequencies of light does photoelectric light react best to? Does it matter? How would it react to an amplified form of cosmic radiation?

Photoelectric light?

The photoelectric effect (when electrons are ejected from a material) usually happens with metals using UV light. Lower (visible or IR) frequencies don't have enough energy to do this. I don't see why one would bother amplifying cosmic radiation. The UV from space is heavily absorbed by the atmosphere.

Imparcticle,
Please define "photoelectric light." ("photoelectric material", as the thread title suggests, perhaps?)

Gonzolo,
I believe you mean "... lower frequencies don't have enough energy ..."?

so i'm very interested in this subject and have never been on a forum, please bear with me.
doesn't cuprous oxide produce a photoelectric effect? i was wondering what else created this effect as well... by definition a photoelectric effect doesn't only exist within metals, but also certain gasses and liquids as well... again please feel free to correct me if i'm wrong.
