I doubt that's what's going on, though. Yes, highly unlikely, since fluors absorb a higher energy photon and emit a lower energy photon. Blue is higher energy than red, not vice versa. Maybe its possible to have a fluor absorb two lower energy photons to emit a single higher energy one (absorb two red, output one blue), but then what will happen to the extra photoelectron kicking around ?
